A harness that fits properly is more comfortable for your dog, safer on walks and lasts longer. The good news is that you can measure at home in about five minutes with a soft tape measure and a few treats.
Step 1: Measure the chest. Wrap the tape around the widest part of the ribcage, just behind the front legs. This is the most important measurement. The tape should be snug but not tight, so you can slide two fingers underneath.
Step 2: Measure the neck. Measure around the base of the neck, where a collar would normally sit. Again, leave room for two fingers.
Step 3: Check your dog's weight. Weight on its own is not a reliable guide, because a lean whippet and a stocky pug can weigh the same and need very different sizes. Use it alongside the chest and neck measurements.
Step 4: Compare with the size guide. Match your chest and neck measurements to the size guide on the product page. If your dog falls between two sizes, choose the larger size and use the adjustable straps to get a snug fit.
How to check the fit. Once the harness is on, you should be able to fit two fingers under every strap. It should not rub behind the front legs, and your dog should not be able to back out of it when you apply gentle pressure on the lead.
Why a padded harness helps. Padding spreads pressure across the chest and reduces rubbing, which matters on longer walks and for dogs with short or fine coats. Our padded harnesses are also washable, so muddy walks are no problem.
