Signs Your Dog’s Harness Doesn’t Fit Properly

7 Signs Your Dog’s Harness Doesn’t Fit Properly

A good dog harness should feel secure but comfortable — not tight, loose, or awkward. If it doesn’t fit quite right, it can lead to rubbing, escape attempts, or even injuries.

But how do you know if your dog’s harness is the perfect match or causing problems? Let’s go through some clear signs your dog’s harness might need adjusting (or replacing).

1. Rubbing or Bald Patches Around the Shoulders or Chest

If you notice fur loss, redness, or rough skin where the harness sits, it’s often a sign the harness is too tight, too loose, or rubbing the wrong way.

Some harnesses have hard edges or seams that can irritate the skin over time — especially if your dog pulls or wears it for long periods.

Our Tweed Harnesses are lined with soft, breathable fabric to help reduce friction while still offering structure and control.

2. The Harness Slides or Shifts During Walks

A well-fitting harness stays in place — no rotating to the side or sliding up the neck. If your dog’s harness shifts constantly, it likely needs better adjustment or a different design altogether.

Look for adjustable straps across the neck and chest for a custom fit.

3. Your Dog Escapes From It

This one’s a big red flag. If your dog can slip out of their harness, it’s either too loose, poorly fitted, or the wrong shape for their body.

You should be able to fit two fingers comfortably under the straps — snug but not tight. Any more space, and it’s escape territory.

4. Signs of Discomfort During or After Walks

Watch your dog’s body language. If they:

  • Scratch at the harness
  • Walk stiffly
  • Keep stopping
  • Act differently after the walk

…they may be trying to tell you something’s not right.

It’s worth switching to a softer, better-fitting harness and watching for improvement.

5. You’re Constantly Adjusting It

If you're spending the entire walk tightening one strap and loosening another, it’s not the right harness for your pup. Harnesses should be quick to put on and stay secure once fitted.

All of our Harness Bundles come with easy-to-use quick-release buckles and adjustable points for a hassle-free fit.

6. Pressure Points Around the Neck or Shoulders

A harness should distribute pressure across the chest and back — not the throat. If your dog coughs or gags when they pull, it might be acting more like a collar.

Choose a harness that’s designed for comfort around the chest and avoids pressure near the neck.

7. The Size Chart Doesn’t Match Your Dog

Many people guess their dog’s size, but breeds vary a lot. Always measure your dog’s neck, chest, and length before buying. If your pup is between sizes, go for the larger option with more adjustment room.

Final Thoughts

A proper harness should support your dog without restricting their movement or irritating their skin. If you're seeing any of these signs, it may be time for a better fit.
