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.
