Quick Answer: Use the two-finger rule — two fingers should slide comfortably under any strap. Not three (too loose), not one (too tight). The chest panel should sit across the breastbone, not near the throat. The belly strap should sit behind the front legs, not on them.
Step by Step Fitting
- Measure first — measure your dog's neck circumference and chest at the widest point behind the front legs. Compare to the size chart.
- Put it on — slip over the head and clip the belly buckle. Don't adjust straps yet.
- Position the chest panel — slide it so it sits across the breastbone. If it's riding up toward the throat, tighten the shoulder straps.
- Position the belly strap — should sit just behind the front legs. If it's on the legs or restricting movement, reposition.
- Check all straps — two fingers under each. Snug but not tight.
- Rotation test — the harness shouldn't rotate around your dog's body. If it does, it's too loose.
Common Fitting Mistakes
- Chest panel too high — near the throat instead of the breastbone. This defeats the no-pull function and can restrict breathing.
- Too loose overall — harness rotates, dog can slip out, clips don't work correctly
- Belly strap on the legs — restricts movement and causes chafing
