The time for complete metabolism of male hormones after a dog is neutered is not entirely certain. It may take a few months to a year. During this period, the dog may still have mating actions of male animals. As the level of male hormones gradually increases, If the dog's behavior decreases, the dog's behavior will gradually decrease. Typically, it is recommended that male dogs be neutered at around eight months of age, or even earlier.

Benefits of neutering dogs:

1. Reduce the risk of pyometra in female dogs. If a female dog has not been neutered, she is prone to diseases related to the reproductive organs, such as pyometra, which can threaten the dog's life. So at a certain point, it is necessary to neuter the female dog.

2. Improve the male dog’s random peeing behavior. Many male dogs will urinate indiscriminately when they are in estrus. If the dog is neutered, this desire of male dogs will be reduced, and the situation of indiscriminate urination will be improved.

3. Reduce the chance of male dogs suffering from prostate diseases. Male dogs that have never been spayed or neutered may develop growths as they age. When the growths in the prostate continue to grow and press on the intestines, they may have difficulty urinating. In severe cases, it can also cause infections. Neutering can reduce the incidence of these diseases.
