Quick Answer

The Slam Dunk FlyHarness fits best when you adjust the chest and girth straps snugly but not tight, and the one-click buckle makes it easy to put on and take off. This guide walks you through the steps for a secure, comfortable fit.

Why Fit Matters for an Active Dog Harness

A poorly fitted harness can rub, restrict movement, or even come loose during a run. The Slam Dunk FlyHarness is designed for active dogs, so getting the fit right means your dog can move freely without chafing.

The harness uses a 3D knitted top layer from premium sneaker material—tough yet breathable—and a ventilated mesh base. This combo keeps the harness lightweight and comfortable, but only if the straps are adjusted correctly.

Step-by-Step Fitting Guide

  1. 1. Loosen All Straps Before Putting On: Unbuckle the harness and fully extend the chest and girth straps. This gives you room to slide it over your dog’s head without pulling their ears or fur. Common mistake: leaving straps too tight, which makes the harness hard to put on and risks pinching your dog.
  2. 2. Position the Harness on Your Dog: Slip the neck opening over your dog’s head so the D-ring sits on the upper back, between the shoulder blades. The chest strap should rest across the breastbone, not the throat. Check that the harness is centered and not twisted before you buckle it.
  3. 3. Secure the One-Click Buckle and Adjust the Chest Strap: Clip the buckle at the side or under the belly (depending on your dog’s size). Tighten the chest strap so you can fit two fingers flat between the strap and your dog’s chest. Too loose? The harness may shift sideways. The one-click buckle should click firmly; if it doesn’t, check for debris or a twisted strap.
  4. 4. Adjust the Girth Strap for a Snug Fit: Pull the girth strap (around the ribcage) until it’s snug but not digging in. You should be able to slide two fingers under the strap. The harness should not lift away from the body when you pull up gently. If the girth strap is too tight, it can restrict breathing; too loose, and the harness may rotate during runs.
  5. 5. Perform a Movement Check: Let your dog walk, trot, and sit. Watch for any rubbing, slipping, or signs of discomfort. The harness should stay in place without shifting more than an inch in any direction. Recheck the fit after a few minutes of activity—some dogs settle into the harness and straps may loosen slightly.
