Quick answer

Measure your dog’s chest girth at the widest point and compare it to the harness size range, then check that the adjustable straps can fine-tune the fit. For the Vera Bradley fleece-lined harness, match your dog’s weight to the size chart and confirm the straps adjust around the chest.

Why chest girth matters more than weight alone

Weight gives a rough starting point, but chest girth is the measurement that determines whether a harness sits comfortably. A dog can be within a weight range yet have a deep chest or narrow build that changes the fit. Always measure the widest part of the rib cage, just behind the front legs, and keep the tape snug but not tight.

When to size up or consider a different style

If your dog’s chest girth falls at the top of a size range and the straps are near their limit, size up for comfort and room to adjust. Dogs with very narrow builds may need a harness with more adjustment points; the fleece-lined harness has adjustable straps but only three sizes, so check the weight capacities carefully. If your dog is between sizes, choose the larger size and tighten the straps rather than squeezing into a smaller one.

How to measure your dog for a harness

  1. Measure chest girth: Wrap a soft measuring tape around the widest part of your dog’s rib cage, just behind the front legs. Keep the tape snug but not tight, and record the measurement in inches. Common mistake: measuring over a thick coat or sweater—measure bare fur for accuracy.
  2. Weigh your dog: Use a pet scale or weigh yourself holding your dog, then subtract your own weight. Compare the weight to the harness size chart. Checkpoint: if weight and chest girth point to different sizes, prioritize chest girth for comfort.
  3. Check the size range: Compare your chest girth measurement to the harness size ranges. For the fleece-lined harness, use the weight capacities as a guide, then confirm the adjustable straps can accommodate your dog’s chest. If your measurement is near the top of a range, size up to allow room for adjustment.
  4. Try it on and adjust: Put the harness on your dog and adjust the straps so you can fit two fingers under each strap. The harness should be snug but not restrict movement or breathing. Common mistake: leaving straps too loose—a loose harness can slip or rub.
  5. Do a movement test: Walk your dog, ask for a sit and a few turns, and watch for slipping, rubbing, or restricted range of motion. Check that the harness does not press on the throat or under the front legs. If you see redness or chafing, readjust or consider a different size.
