Dogs will not have their period again after being neutered. When a pet hospital performs sterilization surgery on a dog, it usually removes its uterus and ovaries, so that the dog will no longer go into heat or have menstruation. The best time to neuter a dog is generally between 6 and 8 months of age, when the dog has not yet begun to go into heat. Surgery during this period can prevent the effects of elevated hormone levels.

Benefits of neutering dogs:

1. Reduce the problem of male dogs running around. If the male dog is not neutered, as soon as they smell the hormonal smell emitted by the female dog during estrus, they will try their best to chase after her. If it is a large dog, the owner really cannot control the dog, and there is really nothing you can do if they run away. But neutering your dog can alleviate this condition.

2. Avoid false pregnancy in female dogs. Some female dogs may show symptoms of pregnancy during estrus, even if they are not mated. They may have bulging abdomens, swollen nipples, and even milk production. This problem can affect your dog's physical health. After sterilization, there will be no such problem.

3. Reduce the risk of pyometra in bitches. 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.
