How do we size our collars?
Stone Creek collars are measured for the end of the buckle to the farthest hole. The farthest hole would be the biggest the collar would go. We have 5 holes each collar 1 inch apart for adjusting size so a 19 inch collar will fit a dog with a 15-19 inch neck. So if your dog’s neck measures 19 inch you would want a 21 inch collar. That would put you in the middle hole in the collar.
