Abstract: A safety collar device prevents choking of an animal when the animal catches the collar on a stationary object while running loose. The device includes a safety enclosure which envelopes the connecting mechanism of the collar (such as the "live" and "dead" rings at the ends of the chain of a choke collar) thus preventing the rings from being caught on the stationary object. The enclosure includes first and second enclosure halves which preferably are hinged to each other and operable between an open and a closed position. When in the closed position, the first and second halves completely conceal the rings of the choke collar. The enclosure has openings for the chain of the collar to pass through but which are sufficiently small to retain the rings within the enclosure. The safety enclosure includes a mechanism for keeping the first and second halves in the closed position.
