Dog Collar Sizing Guide


Proper collar fit is important for your dog’s health and safety.

When fitting a dog collar it should not be loose enough to slip over the dog’s head, nor so tight as to restrict breathing or cause coughing. If fitting for a puppy keep in mind that puppies grow quickly, so it is extremely important to adjust the size of their collars as they get bigger. Choosing an adjustable collar for puppies allows you to size the collar up as the dog grows, but depending upon the breed of the dog most puppies will likely grow to require a whole new collar size. 

To determine the correct collar size for your dog:

To get an accurately sized collar to fit your dog, measure the center of their neck with a cloth tape measure or piece of string, a few inches down from their head. Pull the tape/string snug, but not tight. If you used a piece of string, measure it with a rigid ruler afterwards.

Measure your dog's neck size

Fitting adjustable collars with quick-release buckle:

When purchasing an adjustable collar your dog's measured neck size must fit within the collar’s adjustable length range. For instance, if your dog’s neck measures 13 inches order an 11 - 16 inch adjustable collar.


Fitting collars with a metal buckle:

When purchasing an open-end collar that closes similar to a belt, once you have a measurement of your dog’s neck round the measurement down to the nearest even-sized number. For instance, if your pet's neck measures 19 inches (snugly) you would order the 18 - 21 inch collar.

Our metal buckle dog collars each have 4 sizing holes and are sized from the first hole to the last; the first hole is the smallest the collar will adjust down to, and the remaining holes allow the collar to widen for a comfort fit.
