External medicines for wound healing are not recommended for use on dogs. They will be highly irritating and are not conducive to wound recovery. If you find a wound on your dog, you must first clean and disinfect it, and then use Petsuhe. During this period, the dog should wear an Elizabethan collar to prevent the dog from licking and getting drug poisoning. If the dog does not get better, then the dog should be taken to the pet hospital for examination and treatment to avoid aggravation of the condition and life-threatening consequences.
