Yes, if the Teddy is in good physical condition, healthy and has no diseases, it can be sterilized. If the dog is in poor health or has diseases, it cannot be sterilized. Before the dog surgery, the dog must be vaccinated and make an appointment with the pet hospital. The breeder must take more care of the dog’s wounds and emotions after the surgery. Teddy, who is seven or eight years old, has been in heat for many times before, so he is in need of surgery. After the body changes, the owner will need more comfort.
