How to Measure Your Dog for a Harness That Fits

A harness that fits well is comfortable for your dog on every walk. One that's too loose can slip, and one that's too tight can rub. Measuring before you order helps you choose the right size the first time.

What you need

• A soft measuring tape (a cloth tape works best)
• A treat or two to keep your dog still
• A helper, if your dog wiggles

Step 1: Measure the chest

Wrap the tape around the widest part of your dog's chest, just behind the front legs. Keep the tape level and snug, but not tight. Write the number down.

Step 2: Measure the neck

Measure around the base of the neck, where a collar would sit. Leave room for two fingers to slide under the tape.

Step 3: Check the length

Measure from the base of the neck along the back to the base of the tail if you want a second reference point. Some dogs with long bodies or deep chests fit better in a larger size.

Use the two-finger check

Once the harness arrives, put it on your dog and slide two fingers under each strap. If you can't fit two fingers, loosen the straps. If you can slide in more than two, tighten them. The straps are adjustable, so you can fine-tune the fit over the first few days.

Fit tips that help

• Watch your dog walk for a minute. The harness should sit flat and not shift toward the shoulders.
• Check the fit again after a few walks, since the straps may settle.
• If your dog's size falls between two sizes, start with the size that matches the chest measurement and adjust the straps.
