Adjustable Martingale collars. These nylon collars are special made for use when walking and training greyhounds and other dog breeds with narrow heads. They have an extra loop that gently tightens the collar if the animal pulls, so that the collar will not slip over their head. Greyhound Martingale collars are also great for Whippets, Salukis, and similar breeds.

Overall circumference adjusts from 10"-20", in a 1" width. Collar must slide over pet's head to be put on. 

Please note: We've found that the red collars can bleed if they get wet so we do not recommend red for white or light colored fur.
