Sizing & Fit Guide

Sizing & Fit

Find their perfect fit.

A great fit makes a great walk. Use this guide to find the right size — and reach out if you’d like a second opinion.

How to measure

  • Chest (girth): Measure around the widest part of the chest, just behind the front legs.
  • Back (length): Measure from the base of the neck (where the collar sits) to the base of the tail.
  • Neck: Measure around the base of the neck where a collar would naturally sit.

  • Halo wears a Size S (12 lb Shih Tzu).
  • Coats should slide on with two fingers of room at the belly strap.
