What behavioral changes can I expect after my dog is neutered?

The only behaviors that will be affected by castration are those that are under the influence of male hormones. So for example, a dog’s temperament, training, and personality, are related to genetics and upbringing, not hormones. Neutering does not “calm” an excitable dog, and unless a castrated male dog is overfed or underexercised, there is no reason for it gain weight or become inactive. The undesired traits which are related to male hormones such as sexual behaviours, aggression, and urine marking will change over the course of a few days to a few months. I hope that is helpful information and I wish you the best of luck with Nipper's surgery.

Hello and thank you for your post! In regards to neutering, we typically see changes in aggression and marking. The aggression towards other animals or humans many times will lessen. Marking behavior will sometimes lessen after a neuter but not in every case.

Castration will have the following benefits: No more icky discharge from the penis or prepuce, no incentive to roam and look for females, if the dog shows some aggression, castration will usually lessen aggressive behavior. A lot of entire males are constantly upset and excited if they smell females in heat ( and the smell can travel for a mile and more), No chance of making babies. Here is more info by the ASPCA: http://www.aspca.org/pet-care/general-pet-care/spayneuter-your-pet

It depends on what you mean by "calm him down." Neutering will generally make male dogs less apt to roam in search of females, and may also decrease mounting and urine marking behavior - but otherwise would not be expected to have any significant effects on personality or energy levels.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your question. There are certain health benefits for neutering dogs. Prostatitis (inflammation of the prostate) and certain testicular tumors can be prevented by neutering dogs. However, dogs can also live happy and normal lives intact. Behavioral problems such as territorial aggression and marking may be reduced by neutering dogs as well. Once neutered, Dante will not behave more like a female, this is a misconception and does not happen. He may become more calm and not as hyper or aggressive once he is neutered and this is due to the reduction in circulating hormones following removal of the testicles. I hope this helps guide you in the right direction! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

It is recommended to neuter most males who are not intended for breeding. AT Teddy's age, it will not decrease muscle mass or change the pitch of his bark. Neutered males are generally considered better pets because testosterone can cause pets to be more reactive, aggressive, dominant and territorial. There are also many health benefits.

Hi there. Actually, yes! To reasons not always know to us-changes in the hormonal makeup of our animals (i.e. a recent neuter) can make them smell different. Many theories have been postulated as to why previously accepting partners will turn away the new "smell" and show aggression. Many think it is frustration in the change. Some think it is because they now want to show dominance. Often, we do not ever really know for sure. Normally with time the pair will acclimate again, but I usually recommend supervised playtime until then. I hope this helps!
