To get the most accurate size anxiety vest for your pet, measure the girth of their chest, around the widest part of your dog's torso right behind the front legs, with a cloth tape measure. Pull the cloth tape snug, but not tight. If you don't have a cloth tape measure, you can use a piece of string and measure it with a rigid ruler afterwards. If your dog is in between sizes, we recommend that you choose the larger size.

Chest size is the best measurement for selecting size. Measure just behind the front legs at the largest point.
Sizing tip: When in doubt for a dog in-between sizes, always choose the next size up.
