Size Guide

Chest first. Wrap a soft tape around the widest part of the ribcage, just behind the front legs. Snug, not tight. Then the neck, around the base where a collar sits.

Between sizes? Go up. Thick double coat (shepherd, husky, border collie)? Go up.

Body-type notes

  • Staffies and bulldogs are wide at the chest and narrow at the waist. Pick by chest, then tighten the belly strap fully.
  • Greyhounds and whippets are deep-chested. Pick by chest, expect the neck straps at their loosest.
  • Puppies: buy for today, not for later. A loose harness twists. Free size swap when they grow.
