Usually dogs will not have their periods after being neutered. Neutering a female dog means surgically removing the dog's uterus and ovaries, so the dog will not be in heat or have periods after sterilization. However, if the dog is not completely sterilized and part of the uterine tissue remains in the body, it will also cause bloody discharge. It is recommended to go to the hospital to take a X-ray examination and perform another sterilization operation.

What are the benefits of neutering a female dog:

1. After the female dog is neutered, it can avoid her irritability during the estrus period.

2. After female dogs are sterilized, the increase in stray dogs can be avoided. If the owner does not plan to breed the dog, it is best to have the dog neutered as soon as possible.

3. Neutering female dogs can reduce the prevalence of reproductive diseases such as pyometra, mastitis, and breast cancer.
