These are ideal for large breed dogs, (Rottweiler, American Pit Bull Terrier, German Shepherd, Doberman, Boxer, Bull Terrier, etc.) or they could even be used as a Fursuit accessory (except for the very serious Spiked and Chained collar... that thing could kill someone - it's more of a collector's collar).
