A Thestral is a breed of winged horses with a skeletal body, face with reptilian features, and wide, leathery wings that resemble a bat's. They are very rare, and are considered dangerous by the Ministry of Magic.
A dog collar is a piece of material put around the neck of a dog. A collar may be used for control, identification, fashion, or other purposes. Identification tags and medical information are often placed on dog collars. Collars are also useful for controlling a dog manually, as they provide a handle for grabbing.
If your puppy freezes on a tight line or routinely pulls against it, my first recommendation is to use a halter or harness rather than a collar attached to the lead. Your dog can create serious neck and cervical disk problems by pulling on a collar/leash combination. Next, make sure itâs not you creating the problem.
