3 min readLast reviewed Jun 28, 2026 by petsupplies.co editorial

The options

Front-clip Y-harness

Y-shaped chest piece, leash attachment on the chest ring. The default recommendation for most pet dogs.

Best for, Pullers, puppies, owners new to body harnesses.

Pros

  • Redirects pulling sideways without choking
  • Y-shape leaves the shoulder blades free

Cons

  • Strong, lunging dogs may need a second back-clip point for control

Back-clip harness

Leash attachment on the back, between the shoulders.

Best for, Calm dogs that don't pull; small breeds with delicate tracheas.

Pros

  • Easy to put on
  • No tangle with front legs

Cons

  • Encourages pulling on dogs that already pull (opposition reflex)

Dual-clip (front + back)

Y-harness with both front and back rings, often used with a double-ended leash for two-point control.

Best for, Reactive or strong dogs while loose-leash training is in progress.

Pros

  • Maximum steering on a strong dog
  • Lets you transition to back-only as training holds

Cons

  • Heavier and more expensive
  • Requires a double-ended leash to use both points

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.
