If a dog still gets its period after being neutered, it is possible that the female dog’s uterus was not removed. Dog menstruation occurs due to the regular shedding of the lining of the uterus from the uterine wall. If a neutered dog has only had its ovaries removed but not the uterus, the dog will still have periods. It is best to go to the pet hospital for a check-up. If the operation is not clean, it needs to be re-excised, otherwise it may affect the dog's health.

What are the 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.
