DOG COLLAR SIZING 

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.
