Before you choose to have your dog castrated, it is important to understand that this procedure is not without its risks and complications. Castration has been shown to cause behavioral changes in some male dogs, but these can vary widely among dogs and even between breeds.

Castration rarely prevents territorial aggression completely, so it should only be done after other behavioral problems have been addressed and managed successfully by another means, such as with training and calming pet medication. However, it may also be necessary for some owners who need their dog to live indoors without access to females on any level (for example, if there are existing female pets in the house) or where an entire litter of puppies would not be appropriate due to allergies or other reasons.

Behaviour And Physical Changes

When male dogs are castrated, most of these behavioral problems will be resolved. Dogs who have been neutered are less aggressive towards other dogs and humans and animals they meet on walks. They are less likely to roam or fight with other males that they encounter while walking in the park. They may mark their territory less often, so you won't see them urinating on things in your house anymore!

Some owners find that their dog's personality changes after being neutered. This may be because he is no longer responding to sexual hormones or because he lost some of his masculine traits when he was neutered (such as excitement).

Behaviour Changes In Specific Breeds Of Dog

Pit bulls, known for their protective tendencies, may become more aggressive when castrated. Shih Tzus are often companion dogs. They can be extremely friendly towards other people and animals before being altered but will become territorial in the postoperative period.

German shepherds enjoy being obedient and active, which means they need a lot of exercise during adolescence, especially if they're intact and have been neutered late in life. Neutering early on means that the dog's training doesn't suffer as much since he won't be distracted by mating urges or the desire to leave his owner when he reaches sexual maturity later in life.

Before Castration

Male dogs can exhibit a number of behavioral changes before castration, including:

  • A strong desire to mate. If an uncastrated dog has not been neutered by the time he reaches sexual maturity, he may have a strong desire to mate with any female dogs in heat simultaneously.

  • Aggression towards other dogs and sometimes even people. Male dogs tend to be more aggressive than female dogs; this is especially true if they are unneutered males with high levels of testosterone.

  • Escaping from their owners or roaming away from home in search of a mate (especially if left alone for long periods). An uncastrated male dog is more likely than a neutered one to attempt escape from his yard or run away from home when his owner leaves him unattended outside for extended periods of time (e.g., when going out shopping).


There is no set time period for recovery. Your dog will likely be able to go home with you the same day as his procedure, but he should be kept quiet, given pet meds, and kept in a quiet place for at least 24 hours. No food or water should be given until after this time has passed. Your vet will give you specific instructions and pet supplies afterward to keep your dog quiet. Still, it's important not to rush him into any activity or exercise until he's fully recovered from anesthesia and pain medication like acepromazine and hydroxyzine for dogs.

It's also important that you keep his stitches clean and dry during this period of rest; if they get wet or dirty, they're more likely to come apart prematurely (and it'll hurt). If possible, try not to bathe him too soon after surgery as it could irritate the incision site. But otherwise, keeping him clean is fine as long as there are no signs of infection (if there are red streaks around his incision, then call your vet immediately and get antibiotics for dogs immediately).


If you are considering castration for your male dog, remember that it is a surgical procedure that can have side effects. However, if you are willing to put some time and effort into the recovery process, then it is likely that you will see positive results.
