Will neutering my dog calm him down or change his personality?

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.

Initially probably you won't see much changes, at least for the first few months. Slowly attitude may change towards less markings and other male-sexually related activities (aggression, escaping looking for females and so on). Most of the times these changes influence positively their life in my opinion.

Thank you for submitting your question regarding Popo. Neutering him will help to prevent against certain types of prostate diseases and even some forms of cancer. It will decrease his desire to roam looking for female dogs. It does not affect personality. Every surgery carries the risk of anesthesia. He could experience post-operative swelling or infection. Some adult dogs can gain weight after the surgery. So his calories need to be monitored. These risks are minimal in most cases though. I hope this information helps!

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.

Hello, by castrating Leo he will no longer produce testosterone which is the hormone that stimulates sexual activity. Rarely, some dogs will still have mounting behaviors despite being neutered. You may also consider spaying your female to then likely resolve all of these behaviors. Hope this helps and best of luck

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.
