How Long After Neutering Dog Is Testosterone Gone

After neutering a male dog, many pet owners wonder how long it will take for their dog’s testosterone levels to decrease. Testosterone is the hormone responsible for male traits, including aggression, territorial behavior, and marking. Neutering, or castration, involves the removal of the testicles, which are the primary source of testosterone in male dogs.

The amount of time it takes for a dog’s testosterone levels to decrease after neutering can vary depending on the dog’s age, breed, and overall health. In general, it can take several weeks to several months for a dog’s testosterone levels to decrease to the point where behavioral changes are noticeable.

During this time, pet owners may notice a decrease in their dog’s aggression, territorial behavior, and marking, but it is important to remember that every dog is different.

Neutering, also known as castration, is a surgical procedure that involves removing a male dog’s testicles. The primary purpose of neutering is to prevent unwanted litters of puppies. It is also done to prevent certain health issues that can arise in unneutered dogs, such as testicular cancer and prostate problems.

Testosterone is a hormone produced by the testicles that is responsible for the development of male characteristics in dogs, such as aggression, marking, and roaming. When a dog is neutered, his testicles are removed, and his testosterone levels drop significantly. According to the American Kennel Club, it can take several weeks for a dog’s testosterone levels to decrease after neutering.

However, the effects of neutering on a dog’s behavior can be seen within a few days. Neutered dogs are typically less aggressive, less likely to roam, and less likely to mark their territory. It’s important to note that neutering does not completely eliminate a dog’s testosterone.

1. Some testosterone is still produced by the adrenal glands, which can result in some male behaviors persisting after neutering.
2. However, these behaviors are typically less intense and easier to manage than they were before neutering.
3. Neutering is a common procedure for male dogs that involves the removal of the testicles.

This procedure is done to prevent the dog from reproducing and can also have other health benefits. One of the effects of neutering is the decrease in testosterone levels. But how long does it take for testosterone levels to decrease after neutering? The rate at which testosterone levels decrease after neutering can vary depending on several factors.

1. The age of the dog at the time of neutering can play a role, as younger dogs tend to have higher testosterone levels.
2. The breed of the dog can also affect the rate of testosterone decrease, as some breeds have naturally higher testosterone levels than others.
3. On average, it takes about two to four weeks for testosterone levels to decrease significantly after neutering.

However, it can take up to six months for testosterone levels to fully decrease. During this time, the dog may still exhibit some behaviors associated with high testosterone levels, such as mounting or aggression. It is important to note that every dog is different, and the timeline for testosterone decrease can vary.

• If a dog is exhibiting behaviors associated with high testosterone levels after neutering, it may be necessary to monitor their testosterone levels.
• This can be done through a blood test that measures the dog’s testosterone levels.
• If the levels are still high, additional treatment may be necessary.
• You’ll find that testosterone levels typically decrease within two to four weeks after neutering, but the timeline can vary depending on several factors.

It is important to monitor a dog’s testosterone levels if they are exhibiting behaviors associated with high testosterone levels after neutering. Decreased testosterone levels in dogs can lead to a variety of physical changes. These changes can include a decrease in muscle mass, an increase in body fat, and a decrease in bone density.

Additionally, the dog’s coat may become thinner and less glossy, and the skin may become thinner and more prone to injury. Dogs may also become less aggressive and less territorial after neutering, and may also become less likely to roam or mark their territory. However, some dogs may become more anxious or fearful after neutering.

It is important to note that while neutering can have a significant impact on a dog’s behavior; it is not a cure-all for behavior problems. Owners should work with their veterinarian or a professional trainer to address any underlying behavior issues.

1. One of the most important things to consider after neutering a dog is their diet and exercise.
2. Neutered dogs tend to have a slower metabolism, which can lead to weight gain.
3. To prevent this, owners should adjust their dog’s diet and exercise routine accordingly.
4. A high-quality dog food that is low in fat and calories is recommended for neutered dogs.

Owners should also avoid overfeeding their dog and stick to a regular feeding schedule. Additionally, regular exercise is important to help maintain a healthy weight. Daily walks and playtime can help keep a neutered dog active and healthy. Neutering a dog can sometimes cause changes in behavior, such as increased aggression or anxiety.

To manage these effects, proper training and socialization are crucial. Training should focus on positive reinforcement techniques, such as rewarding good behavior. Consistency is key, and owners should be patient and persistent when training their dog. Socialization is also important to help neutered dogs feel comfortable around other dogs and people.

In some cases, medical management may be necessary to manage the effects of neutering on a dog. For example, if a neutered dog develops urinary incontinence, medication may be prescribed to help manage the condition. Regular check-ups with a veterinarian are also important to ensure a neutered dog remains healthy.

• Vaccinations, parasite control, and dental care should all be addressed during routine vet visits.
• Overall, managing the effects of neutering on a dog requires a combination of proper diet and exercise, training and socialization, and medical management when necessary.
• With the right care, neutered dogs can lead happy and healthy lives.

Do all male dogs calm down after being neutered?

Myth 1: neutering makes dogs calmer – It is widely believed that neutering will help calm boisterous, over-excitable adolescent dogs down. However this is often not the case. In most cases these dogs are receiving insufficient mental stimulation and/or physical exercise for their age and breed and neutering will not alter this. Figure 1. Owners also often inadvertently encourage dogs to show over-excitable behaviour through failing to notice and reinforce calm behaviours. Veterinary nurses should ideally be able to give appropriate advice to owners of over-excitable adolescent dogs, or, if there is no one with suitable expertise within the practice, be able to refer the owner to an appropriately qualified dog trainer or behaviourist because behaviour problems in adolescent dogs are a significant risk factor for them being rehomed or even put to sleep.

How long until neuter is fully healed?

Dog Neuter Recovery Time – There’s no ‘one size fits all’ answer to the question, “How long does it take for a dog to recover from being neutered?” Dogs will take different times for neuter surgery recovery. However, your pup should fully recover in about two weeks, the complete dog neutering recovery time. We’ve outlined the general dog neuter recovery timeline in the table below.

Time Range of Recovery from Neutering	Description
6-9 Months of Age	The neutering surgery happens
First Night	Your dog will likely stay overnight at the vet’s
Day After Surgery	You’ll be able to bring your dog home, potentially with a cone around his head so he can’t reach his stitches, and with a prescription for pain medication
First Couple of Days	Rest for your pup to recover from surgery and so he doesn’t aggravate the stitches, incisions, etc. incurred from the surgery
First Week	Low activity for your pooch, so he doesn’t aggravate the stitches, incisions, etc. incurred from the surgery
After About Two Weeks	Full recovery of your pooch, cone to be removed, and stitches are either dissolved or removed.

This is just a general breakdown of small and large dog neuter recovery. You can discuss the specifics of recovery with your vet. If your little boy appears to be in more pain than he should be, is not acting himself a few days post-surgery, isn’t properly using the bathroom, or if anything else appears not quite right with the recovery process, consult your vet.

Why is my male dog more aggressive after being neutered?

DOES SPAY/NEUTER CAUSE NEGATIVE BEHAVIOR CHANGES IN DOGS? – Many guardians of neutered dogs report significant behavior changes after their dog fully recovers from the neuter surgery. These are generally guardians who chose to neuter their best friend based upon one or more of the following reasons:

1. the recommendation of their vet that neuter would provide the best possible long term physical and psychological health for their dog
2. the assertion of vets and behaviorists that their dog would behave better and become more manageable once neutered (see section ” A New Study Sheds Some Light ” below for further discussion of outcomes)
3. state law requiring that all male dogs adopted from shelters/rescues must be neutered
4. a contract with a breeder that requires neuter at a prescribed time after purchase of the male dog

Alternatively, many people acquire their male dog after he has been neutered and rely on the assertions of shelter staff that once out of the stressful shelter environment and secure in his new home, he will calm down and be better behaved. In either case, guardians may find their dog exhibiting unacceptable behavior, and wonder what it is they have done wrong.

• Unfortunately, as observed by Dr.
• Stanley Coren in Psychology Today, the latest peer-reviewed studies show the behavior changes in male dogs created by neuter are not beneficial as generally asserted by vets.
• In fact, the studies show that neuter actually increases aggression, fearfulness and anxiety in the recipient, as well as making them more difficult to train.

In the San Francisco Bay Area, where almost every male dog encountered in public places (e.g., dog parks, neighborhood walks) has been neutered, a relatively new problem is being observed. Specifically, almost every male dog is described by their guardian as “shy” (i.e., fearful, skittish, retreats from new people or situations), or “does not do well with people/dogs he does not know” (i.e., fearful and aggressive towards people or other dogs that scare him).

1. From our perspective, the body language these dogs exhibit is not that of a confident, happy dog.
2. In fact, this type of behavior in dogs seems unnatural and antithetical to the species.
3. For example, who would ever expect to meet a skittish or unfriendly Golden Retriever? Another common behavior issue guardians of fearful dogs share is reaction to environmental issues (e.g., thunder, fireworks, other loud noises, new places).

The behavior their dogs exhibit ranges from mild anxiety to a full-blown ” panic attack “. Separation anxiety is another undesirable behavior often exhibited in fearful dogs. Most guardians have no idea why their dog reacts as they do, and most are looking to do what they can to help their dogs.

1. As a last resort, some guardians find themselves relinquishing these dogs back to a shelter because the dog’s behavior is not manageable for them.
2. The San Francisco Society for the Prevention of Cruelty to Animals (SF SPCA) is the SF Bay Area’s largest and most progressive adoption agency, and their response to the widespread behavioral problems is to offer specialized ” bravery classes for shy dogs “.

However, they have one very significant caveat: ” These classes are not suitable for dogs who have shown fear-based aggression or reactivity towards people or dogs, including lunging, snapping or having a history or incident of having bitten previously.” Can the evidence of significant canine behavior problems here in the SF Bay Area be tied to our high percentage of spayed or neutered dogs? Are the SF SPCA bravery classes being filled with behavior impaired students that the SF SPCA helped to create through their aggressive spay/neuter campaign? Our study of the stress-response system in spayed/neutered dogs leads us to believe spay/neuter adversely affects the dog’s behavior and personality.

In fact, the documented changes in the stress-response system would predict an increased level of fear and anxiety, which in some dogs can result in aggression. When we examined the peer-reviewed studies on the topic of behavior after neuter (see below), we find the studies confirm behavior is adversely impacted by spay/neuter and these changes are serious and potentially of epidemic proportions.

So let’s see what the experts have to say

Do dogs become nicer after neutering?

Abstract – This study is based upon a written survey of keepers of neutered dogs about the behaviour of 209 male and 382 female dogs. The main findings are: Male dogs show behavioural changes after castration more often and more distinctly than female dogs after neutering.

Behavioural problems in most cases are reduced or have even disappeared after neutering (male dogs 74%, female dogs 59%). At best, hypersexuality and connected problems are changed as expected.49 of 80 aggressive male dogs and 25 of 47 female dogs are more gentle after neutering.10 bitches appeared to be aggressive only after being neutered.

Particularly feeding behaviour changes in 42% of the male dogs and 32% of the female dogs towards an increased intake of food, which also leads to an increase in body weight. This corresponds to decreasing activity, which is indicated by increasing time of rest (male dogs 36%, female dogs 18%) and decreasing motivation to move.

How long does it take for dogs hormones to settle after neutering?

What Is Neutering? – Neutering is a surgical procedure that removes a male dog’s testicles. This prevents the dog from being able to produce sperm, and it also reduces the production of testosterone. Testosterone is the hormone that causes male dogs to develop male features and behaviors.

• Neutering does not instantly eliminate hormonal behavioral patterns in dogs.
• In these situations, patience is required.
• It usually takes around six weeks for a male dog’s hormones to leave his system.
• He may still try to breed with female dogs during that time, and he might even be able to do so.
• Because of the possibility, it’s vital to keep recently neutered dogs away from any unfixed females for the following six weeks.

If your dog appears worried and preoccupied for a few weeks after surgery, that’s normal. That will go away on its own in time.

How does a male dog behavior change after neutering?

Do male dogs experience mood changes after being neutered? – As we mentioned before, the primary benefits of having your male dog neutered lie in an overall reduction of the odds that they develop a wide range of canine cancers. While male dogs who are neutered do experience an increase in aggressive behaviors right after the procedure, neutering can make them much less aggressive over time.

In fact, neutering has bee proven to create a much happier and calmer male dog over time. One of the huge determining factors as to whether your male dog will become more aggressive after being neutered is the type of breed they are. Certain dog breeds are naturally more aggressive than others, so the temporary imbalance in hormones that neutering causes can spike aggressive behaviors in male dog breeds that are predisposed to violent tendencies in the first place.

The most obvious physical change that your male dog will go through is the removal of their testicles; however, once the incision scars heal, it’s barely noticeable. Neutering your dog is great because it bolsters improved health and a longer life overall.

Do smaller dogs heal faster after neutering?

Spay/Neuter Recovery Time – Recovery time varies and tends to depend more on size and age than anything else. Here are some general guidelines for dogs:

A spay is an abdominal procedure that’s far more complicated than a neuter. As such, the dog neuter recovery time is much faster than the dog spay recovery time. Some neutered males may not even act as if anything ever changed. In general, larger, older dogs experience a longer recovery period. For these, it often takes two to three days for dogs to return to their normal selves after a spay and one to two for a neuter. Dogs over three years of age may take a day or two longer to recover. In many instances, older dogs (over six) can take up to a week to feel completely better after a spay or neuter surgery. In general, smaller dogs recover more quickly. The incisions are smaller, and so is the internal anatomy affected, hence less discomfort. The risk of bleeding after surgery is also lower among smaller dogs.

Do dogs personality change after neutering?

Aug 6, 2018 Neutering is recommended for most dogs for several important medical reasons. For example, it is estimated that 60% of dogs that are not neutered will be diagnosed with prostate cancer. But some owners worry about how neutering will affect their dog’s personality,

• The simple truth is that some of your dog’s behaviors are due to increases in testosterone so these behaviors will change after neutering.
• However, your dog’s overall personality will be the same.
• The good news is that the behaviors that will change after neutering are generally considered to be negative behaviors that most dogs want to get rid of anyway.

Running Away/Escaping: Dogs that have not been neutered are guided by hormonal instincts to find a dog in heat. If they smell that female in heat they will do anything to get to that female, including digging under your fence or ignoring your command to stay.

• Dominant Behavior and Aggression: Rising testosterone can make even the calmest dogs become dominant, stubborn, difficult to control, and even aggressive.
• Territorial Marking: Some studies suggest that dogs that have been neutered are less likely to mark their territory with urine.
• In the end, your dog will still be the same dog that you love, even after it has been neutered.

Your dog’s personality and energy level are determined by its environment and genetic makeup, not its reproductive hormones. Most often the only changes that you recognize in your pet will be a decrease in negative habits. They will stay at home and they will become less aggressive.

They will be just as protective of their home as they always have been. In some cases, they may be slightly more fearful and sensitive to touch after the surgery, but that is tao be expected as they adjust to the changes in their body. These behaviors should fade as his recovery continues. Once they recover from the surgery, they should have just as much as energy, courage, and love as they did before.

Some people worry about the psychological effects of neutering. It is important to understand that dogs are different than humans. Male dogs do not take ownership of the pups, so they will not be disappointed if they never experience fatherhood. They also do not have a sexual identity like humans do.

• They don’t feel like a man because of their reproductive hormones.
• They don’t have a concept of masculinity.
• They are simply acting on instinct that is meant to preserve their species.
• Neutering will simply inhibit those instincts by lowering their testosterone.
• After neutering, your dog will be healthier, easier to train, and more affectionate.

You won’t have to chase after your dog as he chases a dog in heat. You won’t have to clean up the pee that your dog used to mark his territory on your futon. Your dog will be less stubborn and easier to train. You will both be happier and you will be helping to control the overpopulation of the species.

What happens to dogs balls when they get neutered?

What can I Expect upon Discharge from the Hospital? – The scrotum is often swollen in the first few days after surgery, leading some people to wonder if the procedure was really performed. If the dog is immature at the time of neutering, the empty scrotum will flatten out as he grows.

Is it okay to neuter a dog at 1 year?

For male dogs: – The signs of sexual maturity in male dogs include lifting their leg to urine mark (even in the house), humping, and overprotectiveness. Some of these behaviours can start at an early age and intensify as they continue to mature until 12 months, or even older for large breeds.

1. During this time they build more muscle as their growth plates close.
2. This maturation of their musculoskeletal system can help prevent certain orthopedic injuries later in life, especially in large breeds.
3. There is also some evidence that certain cancers may be less likely if they are allowed to have some time to reach sexually maturity.

Male dogs that are left intact through adulthood and into their senior years can encounter prostate disease, perineal hernias, perianal tumors, and testicular tumors. When should I neuter my male dog? Small dogs do not have as many orthopedic issues, therefore it is fine to neuter them on the younger side at 6-12 months of age.

Do dogs usually cry after neutering?

Is It Normal For Dogs to Whine After Neutering? – So, what about male dogs? Is it normal for them to whine after a neuter surgery? Following a general anesthetic, some dogs cry and whimper quite loudly. Neutered dogs usually feel some degree of discomfort immediately following their procedure.

It is not unusual for your dog to whine or whimper after being neutered, although some dogs can tolerate pain more than others. A dog’s whining after neutering is completely normal. Your dog is probably okay if he is eating, drinking, walking, and going to the bathroom without any problems. He may be a bit wobbly or sleepy the day of the procedure as the anesthetic wears off over the next 24 hours.

Neuter surgeries cause temporary discomfort that lasts just a few days and should disappear after a week. If your dog seems to be experiencing any pain or discomfort for more than a couple of days, it’s a good idea to contact me for further advice.

How long are male dogs aggressive after neutering?

How Will Male Dogs Act after Being Neutered? – Neutering shouldn’t have much of an effect on dog behavior, but that doesn’t mean that there won’t be some temporary short-term changes to your dog. You might notice your neutered dog is more anxious, clingy to its humans, or even angrier than usual. You’ll be happy to know that behavioral changes in your male dog should disappear after a couple of days, but this recovery could take up to a week if your dog is older.

Are male dogs less energetic after neutering?

Your Dog May Be Less Energetic – Spaying and neutering can also have an impact on your dog’s energy and activity levels. Some dogs may become less active or less interested in play after neutering, while others may become more relaxed and content. It’s difficult to predict exactly what will happen in each case, particularly if your dog is chock full of energy.

Ultimately, the effort you put into training your dog from a young age will have the greatest impact on their personality. To ensure they’re receiving the appropriate amount of physical activity after they’ve been spayed or neutered, monitor your dog’s current activity level and adjust their exercise routine appropriately.

That may mean more exercise — or less. Your dog’s pain medication, not to mention the cone of shame, will put a damper on things immediately after the procedure. Your vet will likely advise you to take things easy for a few days.

What to expect after neutering a male dog?

What to expect after neutering your dog – After the neuter, assuming everything went according to plan, your dog will be discharged into your care. Most sutures used in neuters are absorbable, which means you will not have to return to the hospital to remove the stitches.

1. Most dogs recover relatively quickly from neutering.
2. A little wooziness is not unusual; post-anesthesia anxiety and fussiness is normal.
3. Young dogs may want to return to play as soon as the same day.
4. However, dogs should be kept calm for 10 to 14 days after surgery, or however long your veterinarian recommends.This means restricting play and exercise to short leash walks for elimination purposes and keeping your pup indoors in a clean, dry environment.

If possible, consider crating your dog when you are not around to keep him calm. Finally, keep an Elizabethan collar (e-collar) on your dog to prevent him from licking the wound, which can cause damage to the incision site and can open up the area to infection.

Most dogs will not defecate for 1 to 3 days after surgery. This is totally normal and no cause for alarm. You may notice a small amount of bloody fluid collecting in the remaining scrotal sac. While this usually disappears on its own within two weeks, in rare cases where large amounts of fluids collect, a second surgery may be required.

If you’re worried about it, give your vet a call. Diarrhea and vomiting, while uncommon, may be other post-surgery behavior that would warrant a call to the vet.

How does neutering affect a male dog behavior?

Effects of neutering on undesirable behaviours in dogs The evidence surrounding the behavioural effects of neutering is conflicting, so it is important to consider each case individually and discuss possible benefits and contraindications with owners The use of surgical neutering is widespread, utilised for its health benefits (Forsee et al,, 2013; Yates and Leedham, 2019), reducing sexually dimorphic behaviours (Downes et al,, 2015) and unwanted behaviours (Roulaux et al,, 2020), and population control (Wongsaengchan and McKeegan, 2019).

Challenges arise around appropriate neutering age, individual clinical cases and sex of the dog (Diesel et al,, 2010). The UK is reported to have the highest worldwide neutering rate (Heimendahl, 2010), with the informing that 71 percent of the canine population has been neutered, despite this decreasing from 81 percent in 2017.

Conversely, in many Northern European countries ovariohysterectomy and castration procedures are monitored and are even prohibited in some locations by animal welfare acts (Heimendahl, 2010). Current, with anecdotal evidence valuing routine neutering for modifying behaviour, emphasising that neutering will improve behaviour, producing a calmer, well-rounded individual.

Scientific literature fails to create a coherent, convincing argument, with many studies evidencing positive, negative or minimal impact of neutering on overall behaviour. The hypothalamic–pituitary–gonadal (HPG) axis is essential for homeostatic governance of reproductive functioning. Sex-related hormones and receptors are disseminated throughout the brain’s limbic system, functioning as neuromodulators and neurotransmitters, affecting sociosexual behaviour and emotion (Carter, 1998).

In humans, elevated levels of testosterone correlate with higher levels of confidence and resilience (Eisenegger et al,, 2017; Cherki et al,, 2021). Increasing oestrogen levels in women with depression positively impacts recovery (Lascurain et al,, 2020) and higher oestrogen levels beneficially impact life satisfaction (Sengül and Kasten, 2018).

1. Correspondingly, entire dogs are “bolder” than neutered dogs, with entire males more confident than entire females (Starling et al,, 2013).
2. In humans, elevated levels of testosterone correlate with higher levels of confidence and resilience Correspondingly, entire dogs are “bolder” than neutered dogs, with entire males more confident than entire females Domestic dog aggression jeopardises dog welfare, and family- and stranger-directed aggression risks human health and safety, remaining a primary cause of shelter relinquishment and euthanasia.

Neutering was used by 58 percent of Dutch dog owners for “correcting” unwanted behaviour, but failed to reduce aggression in most dogs (Roulaux et al,, 2020). Marginal increases in levels of stranger-directed aggression in neutered dogs have even been noted (Farhoody et al,, 2018), and earlier work showed neutering failed to improve stranger-directed aggression (Neilson et al,, 1997).

Neutered males have also been found to be more “emotionally unstable”, display a greater tendency for aggressive behaviour (Kaufmann et al,, 2017) and exhibit higher rates of owner-directed aggression (Guy et al,, 2001; Hsu and Sun, 2010). Conversely, other publications concluded human-directed (Matos et al,, 2016) and conspecific aggression (Casey et al,, 2012) were less prevalent in neutered dogs.

Female spayed dogs are highly represented in many studies with a higher likelihood of presenting with human-directed aggression (Podberscek and Serpell, 1996; Guy et al,, 2001; Kim et al,, 2006; Bálint et al,, 2017; D’Onise et al,, 2017) and reactive behaviour (Lorenz et al,, 2019) compared to neutered males and intact females, but this message is not coherent (Casey et al,, 2012).

Resource guarding is highly represented in neutered dogs in comparison to intact dogs (Reisner et al,, 2007); however, it was neutered males who were more likely to be implicated in human-directed growling and resource guarding rather than females Resource guarding is highly represented in neutered dogs in comparison to intact dogs (Reisner et al,, 2007); however, it was neutered males who were more likely to be implicated in rather than females (Guy et al,, 2001; Jacobs et al,, 2018).

Children hospitalised with resource guarding-related dog bites were statistically more likely to have been bitten by a neutered dog (Jacobs et al,, 2018). While evidence and links between neuter status and obsessive-compulsive disorder (OCD) in dogs are minimal, data suggests neutered male and female dogs are more likely to present with OCD-type behaviour (Overall and Dunham, 2002; Dinwoodie et al,, 2019); however, neuter status and dog sex could not predict the form of OCD developed.

Fearful behaviour can result in strained relationships between dogs and humans, welfare concerns, long-term health problems and reduced longevity, particularly during chronic stress (Dreschel, 2010). Neutering has been implicated in increasing anxiousness in pet dogs (Kaufmann et al,, 2017; Puurunen et al,, 2020), with dogs neutered before the age of one year old presenting with exaggerated fearful responses (McGreevy et al,, 2018; Stellato et al,, 2021).

Non-social fear was more liable to be seen in neutered dogs (Hakanen et al,, 2020), and rates of noise phobia were highly represented in neutered dogs (Vucinic et al,, 2013). Sex may influence unwanted behaviour development, with neutered males more likely to present with aggression and neutered females with anxiety (Cannas et al,, 2018).

• Links between neutering and anxious behaviour appear more conclusive and consistent than aggression, with published evidence suggesting neutering is not an appropriate strategy for reducing anxious responses and may magnify anxious and fearful tendencies.
• Links between neutering and anxious behaviour appear more conclusive and consistent than aggression, with published evidence suggesting neutering is not an appropriate strategy for reducing anxious responses and may magnify anxious and fearful tendencies.

As defensive aggression has been linked to anxiety and fear (Notari et al,, 2020), dogs exhibiting consistent anxious responses may pose a higher risk for owner-, stranger- or conspecific-directed aggression. It may be prudent to consider non-permanent, for dogs presenting with fearful responses, prior to gonadectomy.

• Police dog training was adversely affected by gonadectomy (Fattah and Abdel-Hamid, 2020), with entire dogs significantly more trainable than neutered dogs.
• Conversely, castrated male Shetland Sheepdogs appeared more trainable (Serpell and Hsu, 2005); however, in this study only 11 breeds were assessed and the authors cautioned against extrapolating these findings to other breeds.

Delayed neutering (between 7 and 11 months of age) increased trainability and focus, and reduced hyperactivity, reactivity and prey drive compared to earlier neutering prior to 7 months (Zlotnick et al,, 2019). Other publications showed minimal differences in trainability between neutered and entire dogs (Serpell and Hsu, 2005; Yates and Leedham, 2019).

When considering “miscellaneous” unwanted behaviours, there appears to be no beneficial effect of neutering. One large-scale review highlighted that neutered males and females were nearly twice as likely to exhibit behavioural problems (Dinwoodie et al,, 2019), and another identified that excessive activity, barking and aggression are more prevalent in neutered dogs (Chung et al,, 2016).

A longitudinal large-scale study showed that the majority of behaviours assessed via the Canine Behavioral Assessment and Research Questionnaire (C-BARQ) were less prevalent in dogs with longer exposure to gonadal hormones A longitudinal large-scale study showed that the majority of behaviours assessed via the (C-BARQ) were less prevalent in dogs with longer exposure to gonadal hormones, and only two behaviours more prevalent with delayed neutering: howling and urine-marking (McGreevy et al,, 2018).

1. The authors concluded that early neutering may have some beneficial effects, but may also have other undesirable consequences, including increased aggressive and fearful-related behaviours.
2. Despite inconclusive evidence to suggest that neutering reduces reproductive-related behaviours such as roaming (McGreevy et al,, 2018), the benefits for reducing the likelihood of unwanted breeding cannot be diminished.

Problem behaviours associated with seasonality or pseudopregnancy in bitches, or urine-marking, sex-related mounting and some forms of aggression in male dogs may improve post-neutering. However, behavioural intervention may also be required in these cases (Warnes, 2018).

Literature and methodologies in this area are problematic, as pre- and post-neutering research typically relies on owner reflection on dog behaviour which can be problematic, or relies on recruiting neutered and unneutered dogs with extensive variables between groups. Many methodologies cannot comprehensively evaluate the impact of genetics, epigenetics, environment, social stability and prior training alongside the removal of reproductive hormones.

Many methodologies cannot comprehensively evaluate the impact of genetics, epigenetics, environment, social stability and prior training alongside the removal of reproductive hormones To further existing understanding, research needs to encompass behavioural evaluation of dogs pre- and post-neutering, which poses ethical issues if surgical gonadectomy may perpetuate existing behavioural issues.
