It's really easy! Simply wrap a measuring tape around the middle of your dog's neck, which is where you want the collar to sit. Use the exact measurement—don't add any slack, we'll handle the proper fit!

Our sizing method applies to all large breed dogs including American Pit Bull, Pitbull, Doberman, Rottweiler, Great Dane, Bull Mastiff, Cane Corso, English Bulldog, American Bulldog, German Shepherd, Boxer, and many more.
