To properly measure for our dog collars, use a soft measuring tape and gently wrap it around your dog’s neck. Adjust so the tape measure is as snug as your dog would wear their collar. Remember, long hair dogs often have a little extra wiggle room due to their coat. Perri’s recommends if your dog measures between two sizes, to order the smaller size. As a natural product, leather does stretch over time.
