Why a Harness Is Usually Better Than a Collar for Walking

A collar puts all leash pressure on your dog's neck and throat. For dogs that pull — which is most dogs — this creates repeated stress on the trachea and cervical spine. Small breeds and brachycephalic dogs (Pugs, Bulldogs, French Bulldogs) are especially vulnerable to collar-related injuries.

A harness distributes pressure across the chest and shoulders, which is far safer and more comfortable. A front-clip no-pull harness also gives you a mechanical advantage against pulling — when your dog lunges forward, the leash redirects them sideways toward you, naturally discouraging the behavior.

Types of Harnesses

Front-Clip (No-Pull) Harness

The leash attaches to a D-ring on the chest. When your dog pulls, the leash redirects them toward you — discouraging pulling without any pain or correction. This is the best choice for dogs that haven't mastered loose-leash walking.

Our No Pull Pet Harness uses a front-clip design with a padded chest plate, reflective stitching for night visibility, and an easy step-in design. Available in XS through XL to fit most breeds.

Back-Clip Harness

The leash attaches to a ring on the back. More comfortable for dogs that already walk well on a leash, but gives you less control over strong pullers. Good for small dogs and calm walkers.

Dual-Clip Harness

Has both front and back attachment points. Use the front clip for training walks and the back clip for casual outings. The most versatile option if you want one harness for multiple situations.

Key Features to Look For

Fit and adjustability: Look for multiple adjustment points (chest, belly, and shoulder straps) so you can dial in a snug, secure fit. You should be able to fit two fingers under any strap, but no more.

Padding: Especially important for dogs that wear a harness for extended periods. Padded chest plates and shoulder straps prevent chafing and pressure sores.

Reflective stitching: If you walk in the early morning or evening, reflective elements on the harness make your dog visible to drivers and cyclists. Our No Pull Pet Harness has reflective stitching built in.

Ease of putting on: Step-in harnesses are easier for most dogs than overhead designs. If your dog is anxious about having things put over their head, a step-in is the better choice.

Durability: Look for reinforced stitching at stress points (especially the leash attachment ring) and hardware that won't rust or break.

How to Measure Your Dog for a Harness

Most harnesses size by chest girth — the widest part of your dog's chest, just behind the front legs. Measure with a soft tape measure and compare against the manufacturer's size chart. When between sizes, go up.

Final Thoughts

For most dogs, a front-clip no-pull harness is the safest and most practical choice for walks. Shop our No Pull Pet Harness — free shipping to the Lower 48 states.
