Size Guide

A well-fitted piece is a comfortable one. Here's how to measure your companion and choose the right size.

How to Measure

  • Neck: Wrap a soft tape around the base of the neck where the collar sits, leaving room for two fingers.
  • Chest (girth): Measure around the widest part of the chest, just behind the front legs.
  • Back length: Measure from the base of the neck to the base of the tail for apparel.
When a measurement falls between two sizes, size up for comfort — especially for growing puppies and thick-coated breeds.
