To get the most accurate size harness for your furry best friend, measure the girth of their chest, just behind the front legs, with a cloth tape measure. Pull the tape snug, but not tight. If you don't have a tape measure, you can also use a piece of string and measure it with a rigid ruler afterwards. Make sure there’s enough room for about two fingers between the harness and your pup’s chest.
Chest Girth: To make sure you purchase the right size harness for your canine companion, wrap the tape around the widest part of your dog’s torso, right behind the front legs. This is the most important part!
Lower Neck: Harnesses sit lower on the neck than collars, so measure from the lower part of the dog’s neck to make sure it's the right size for your pal.
