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.
By far the most common collar is the flat or rolled collar that fastens with a plastic clip or a buckle. These collars are the most convenient to slip on and off and are handy because they can hold your dogâs identification, rabies, and license tags. Even though this type of collar retains its size, the collar can become a hazard.
