The head size of many breeds (including Whippets and Greyhounds) is smaller than their neck so keeping a collar securely fitted can pose problems.
BlackDog Sighthound Collars are designed for dogs with heads smaller than their necks. These collars are designed to tighten if a dog tries to slip it's collar, while the extra thick webbing and tapered throat pad ensures that the dog's neck and soft hair are protected and supported. While this collar is designed specifically for sight hounds, it may also be used on many soft haired breeds such as Vizslas, German Shorthaired Pointers and Dobermanns, provided this collar is large enough to be fitted over the dog's head.
