My Dog Is Aggressive After Neutering

When we discuss aggressiveness in dogs, we refer to the behaviors which pose a threat to other animals or people. It is one of the most serious behavioral problems in dogs due to such threat. An aggressive dog will display their aggressiveness in various ways, not all of them as obvious as others. They can growl and snarl their lips, but they may also bristle their hair and turn their ears back. Biting and attacking are the most concerning behaviors.

Aggression arises when the dog's response to a situation causes insecurity or conflict. Their reaction is a means to take back control. In other words, an aggressive reaction is the means to free themselves from the stimulus which makes them feel threatened. It is a self-reinforcing behavior. When a dog is aggressive and others stay away from them, they are more likely to repeat it. Aggression in dogs is one of the most common reasons for dog abandonment.

Causes of canine aggression

There are multiple causes that can lead to aggressiveness shown by a dog, such as fear or defense of resources. We may also witness aggressive behaviors when males are confronted by a female in heat or vice versa. Females can compete over a single male just as males do the same for a female. This is why neutering is often seen as the best solution to aggression problems in dogs. As we will see, there are other causes which require different solutions.

The hormone testosterone can act by encouraging certain aggressive behaviors. Neutering differs according to sex. Castrating a male dog removes their testicles. Spaying a female dog removes her ovaries and uterus. For this reason, neutering only affects sexually-dimorphic behaviors, i.e. those which depend on the action of sex hormones on the central nervous system. Examples include territorial marking behavior or intrasexual aggressiveness, meaning aggression towards the same sex.

In females, spaying can help the dog avoid aggression linked to periods of reproductive activity. Since they are unable to reproduce they won't experience phantom pregnancy or try to compete with other dogs. It should be pointed out that the results of neutering are variable between individuals. Although we can point to likely outcomes, we cannot guarantee a dog's behavior. Previous experience of the animal, age and other circumstances are also influential.

Additionally, the effects of neutering on a dog can take time to manifest. This is due to the differing time it takes for the testosterone to leave the body.

If we have neutered our dog and notice they become aggressive, it does not have to be related to a behavioral problem. Some individuals return home stressed, disorientated and in pain. An aggressive reaction may simply be a valid reaction from a traumatic event. In these cases, the aggression should disappear in a couple of days or improve with pain management treatment.

When a dog shows aggression related to sexually dimorphic behaviors, they should be under control a few months after being neutered. However, we should also take other measures to ensure stable behavior. However, in females, spaying can increase aggressive reactions. It is most common in bitches which have been neutered very young, i.e. before they are 6 months of age.

For dogs which react aggressively to strangers before they are neutered, this behavior can worsen. This is because estrogens and progestogens help inhibit aggression in female dogs. Eliminating them can also eliminate these inhibitions. This is why there is some controversy in neutering aggressive female dogs. However, if a dog is aggressive after surgery, it is likely not related to the hormones which have been eliminated.

If the aggression after neutering is due to stress resulting from the procedure, it will eventually subside once they regain stability and the pain lessens. The best thing to do is to give them time and space. Do not punish or try to cajole them, but ignore them. It is essential not to reinforce this behavior so they don't see it as a helpful way to get what they want. If this happens it can manifest in other situations.

Situations in which the dog was previously aggressive require action. Canine aggression should never go unchecked. It is essential we treat it from the first time we observe it. Ignoring the problem is only likely to make it worse. This can have very negative consequences on other animals and people both inside and outside the home. The longer a dog is aggressive, the more difficult it will be to counteract it.

The first thing we need to do is take the dog to a veterinarian. There are some diseases which can lead to aggression as a clinical symptom. If the vet determines our dog is healthy, then we need to speak to a dog trainer or canine ethologist. They will evaluate the dog's behavior and look for a cause of the problem. They will then be able to suggest and implement the necessary measures to solve it.

Stopping aggression after neutering in our dog is a problem which requires our involvement as dog guardians. We can be assisted by using smartphone applications. These apps allow us to not only communicate in real time with the trainer, but they can contact the veterinarian directly when needed. The monitoring of the dog and the implementation of these measures for treatment is facilitated.

Aggression in dogs can be solved, but it is difficult. It requires time, perseverance and, in most cases, the help of a professional. To best ensure guardians and professions work together productively, apps can be an essential tool.
