How to Measure Your Dog for a Step-In Harness (And Eliminate Chafing)
Most harness returns happen because ribcage depth varies wildly by breed. Follow this two-step tape measure check before ordering.
1. Measure the widest point of the ribcage, not just weight
Use a soft tailor's tape just behind the front legs where the sternum curves deepest. Deep-chested breeds like French Bulldogs, Corgis, and Dachshunds frequently need one size larger around the chest than their body weight alone suggests.
2. Apply the two-finger armpit clearance check
After clipping both side buckles, slide two flat fingers beneath the chest strap and behind the front elbow. Proper clearance prevents underarm rubbing on brisk 45-minute walks while keeping the harness escape-resistant.
3. Front D-ring vs. back D-ring attachment
Clip your leash to the front chest D-ring when teaching loose-leash manners in busy neighborhoods; switch to the back D-ring for relaxed sniff walks or crossbody trail outings.
