Harness Size Guide

Measure your dog at the widest point behind the front legs. If your dog falls between two sizes, size up.

How to measure:

  • Chest: the widest point behind the front legs
  • Neck: the base of the neck where a collar sits
  • Girth: around the deepest part of the ribcage

Measurements should be snug but with room to slide two fingers underneath.
