Black Dog Wear Whippet Collar (28-36cm) is specifically designed for Whippets. Black Dog has worked with Whippet breeders to scale down the sighthound design and produce this elegant and practical collar specifically for the breed. The collar has a wide, tapered neck pad and a tightening action for security, so your dog can't slip its collar. SIZE: Adjustable from 28-36cm Please also see the Black Dog Two-tone Whippet Collars for more colour choices.
