Dog Acting Weird After Neutering

Dog Acting Weird After Neutering? Housebreaking Regression & More!

It is always a good decision to neuter your dog, it not only helps control the dog population but also reduces the risk of health issues including canine tumours. Neutering is a safe procedure for pups and dogs, but most owners notice some behaviour changes in their pets after the procedure. One of the most common complaints is that the dog acts weird right after getting neutered.

In this guide, let us try to understand what changes you should expect in your pet’s behaviour after neutering and what you can do to calm them down.

Dog Acting Weird After Neutering? Here’s What To Expect

Neutering your male dog has several benefits for you and the pet. However, it is important to know what you should expect after the surgery. While the recovery from this procedure is pretty quick and straightforward, dog owners can notice sharp changes in the pet’s behaviour when they are brought home after neutering.

Neutering is one of the most effective ways to reduce a male dog’s sexual desire. But the procedure can bring about many other behavioural changes you may not expect. One of the most commonly seen effects in a neutered dog is aggression. You may find your dog aggressive right after the procedure but neutering can make them much calmer over time. Sterilizing is, in fact, one of the best ways to make the dogs calm and happy.

Here is what you should expect from your dog after neutering:

Keeps sitting

Operated dogs are likely to experience some lethargy and fatigue. So your pet may either keep sitting or even sleep a lot. However, if you see any strange signs like difficulty breathing or pale gums, contact the vet immediately.

Appetite loss

The dog has recently undergone major surgery and may take a few days to return to its normal life. While some dogs may become normal instantly, others may not show much interest in food and drink. This should resolve on its own as the dog recovers. Make sure you give enough fluid to the dog to prevent dehydration.

Disoriented and weird

It is the anesthesia given during the surgery that makes the dog groggy so keep a watch on him or he may fall off. Neutered dogs are likely to behave strange and weird after the procedure because of the stress, anxiety, and pain associated with the experience.

Housebreaking Regression After Neutering

Many dog owners report housebreaking regression in their otherwise disciplined dog after neutering. It is completely normal for your previously housebroken dog to start urinating in the house after getting neutered. The reason can be hormonal changes from the procedure changing the urinating needs and patterns of the dog.

Sometimes, it can be the incision or swelling from the surgery that can get in the way of normal dog behaviour. However, the problem resolves on its own in a week or two without any complications. To handle this behaviour, you can try isolating the dog in a small room for a few weeks or supervise him to notice any unexpected activities. Look for signs of restlessness and check with your vet if you feel the need.

Potty Training Regression After Spaying

Pet owners commonly report problems associated with potty training regression after spaying or neutering their dogs. Seeing your dog urinate here and there in the house is frustrating, particularly when the pet has gone through complete potty training as a pup. However, such a regression is quite common after spaying and neutering and can be easily corrected with some patience and methods.

The best thing is that you need not worry because potty training regression after spaying does not mean you will have to train the dog from scratch. The rapid changes in hormones that come from spaying or neutering are responsible for pee accidents. Sometimes, the dog shows such strange behaviour from the anxiety and discomfort associated with the procedure and should go away on its own as he recovers.

You can handle potty training regression by crating the dog and keeping a close watch on them. The problem should resolve in about two weeks as the pet gets accustomed to the changes in the body. It is important that you don’t get angry with the dog for such accidents.

Dog Acting Scared & Restless After Neutering

Neutering is a procedure that reduces the sex drive of the dog and inhibits its reproductive ability. However, it does not bring a lot of behavioural changes or a change in attitude towards people. It is natural to see restlessness and aggression in recently neutered dogs. The reason is the pain experienced from the surgery. You might need some medications prescribed by the vet to handle the pain and discomfort.

There is also a chance that the dog is in trauma from the experience at the hospital, the pain, and the surgery. He might need a week or two to calm down and recover. As the dog recovers, his physical activities are limited and he might get bored from sitting. This change in routine is responsible for the behavioural changes you notice after neutering.

As the dog heals after the surgery, it is important that you keep him calm, confine, supervise and play with him. If you see the dog acting scared, try to assure him that you love him and make him feel secure. You should also make sure the neutered dog is kept away from other pets in the house for a few days. You can consult a vet or specialist if you don’t see a change in the dog’s behaviour after 8-10 days.


Neutering is a safe procedure that does not negatively change your dog’s personality, as commonly believed. The fact is that it prevents aggression, territory marking, roaming, and other unwanted behaviour. It is common to see a temporary behavioural change in dogs after neutering but it should resolve within days. Consider caring for the dog after the surgery, create a calm environment, and keep him entertained for a speedy recovery.
