How long to wear an Elizabethan collar after sterilization?

Wear an Elizabethan collar for seven days after sterilization. The purpose of wearing an Elizabethan collar on dogs is to prevent the dog from licking the wound, because the wound will itch during the healing process. Generally speaking, dogs can return to their normal life in about ten days after surgery. Neutering a dog can reduce the risk of disease, extend the dog's life, and make the dog's temperament more docile.
