Sizing Guide

We at ServiceDogVest.com manufacture and offer the highest-quality vests, harnesses and

accessories for your dogs’ needs. Here you will know how to properly size your dog for the

proper size vest. Our Service dog vests come in multiple sizes: XXSmall, XSmall, Small,

Medium, Large and Extra Large. These sizes range from our XXSmall Size of 11”, to our

Largest Vest opening to 45”

The best way to measure you dog would be to use a flexible tape measurer, or string. Using the

tape or string, wrap around your dog’s rib cage directly behind its’ front legs. Measure twice for

accuracy.
