Fit checklist
- Two fingers fit flat between the harness and the dog at every strap.
- Y-shape sits in front of the shoulder, never across the shoulder blades.
- No rubbing in the armpit when the dog walks 50 steps.
- Buckles sit on the side or top, never under the armpit.
- Re-check fit every 4 weeks for puppies; every 3 months for adults.
What to skip
- Horizontal-strap (T-shape) harnesses, they cross the shoulder and restrict gait.
- Tight no-pull harnesses that tighten under the armpit when the dog pulls, they cause pain, which is exactly what AVSAB's humane-training position warns against.
- Retractable leashes on any harness, they teach pulling and cause hand injuries.
