If the dog's licking wound becomes inflamed after sterilization, you need to use saline or hydrogen peroxide to clean the wound, and then apply anti-inflammatory ointment. The dog should usually wear an Elizabethan collar to prevent the dog from licking the wound. If the situation is serious, you can also give the dog some antibiotics. The diet should be mainly light, and nutritional supplements should be strengthened. It is best to feed boiled chicken, egg yolks and other foods.
