What is the horn worn around the dog’s neck The horn worn around the dog’s neck is an Elizabethan collar, also called a protective collar or a collar of shame. The Elizabethan collar is shaped like a horn and is designed to prevent the dog from licking or scratching the wound. When a dog wears an Elizabethan collar, the dog’s space for movement is somewhat limited and can be well restrained from acting out.
