Collar Sizing Information Traditional dog collars are available in a variety of styles, colors and widths. They should ride high on your pet's neck, but not loose so that it slides down near the top of his shoulder blades. Dog Collars should be snug with enough room to fit two fingers between your dog's neck and his collar. For your dog's safety, the collar should not be loose enough to slip over the pet's head. Collars should also not be so tight as to restrict breathing or cause coughing. Check collar size frequently on growing puppies.
