The time of sterilization surgery:
If you want to sterilize your pet at home, the difficulty that everyone will fully consider at the beginning is how much is the best pet to sterilize. Dogs usually ensure estrus period around eight months after birth.
The female dog has her first time here, and will be born twice a year later, which is called the "breeding period", which may be a pregnancy stage.
On the one hand, after the male dog reaches the estrus period, in order to better cause the "breeding period" of the female dog, a series of actions by perfectionist female dogs took place. For example, they keep barking, go to areas where there are female dogs, and fight with other male dogs to fight for female dogs. In short, I just can't calm down. Therefore, it cannot be a female dog. Male dogs need to be sterilized about 5 to 6 months after birth before reaching estrus.
In addition, if your puppy has missed the best time to sterilize the puppy after being over one year old, there is no need to worry. Sterilization at this moment will not cause great harm to the puppy. It is very likely that the dog's personality will change after the sterilization surgery.
