Dog Harness & Apparel Sizing Guide

Need help figuring out exactly which size harness or apparel to get for your pup?

Cuchello Harness & Apparel Sizing Guide


How to measure

  1. Simply measure around the widest part of your dog's rib cage with a flexible tape measure or string
  2. Dog harnesses should be snug with enough room to fit two fingers under the harness
  3. Harnesses should not be so tight that they restrict breathing or cause coughing. We recommended add 1 inch to your measure

How to choose size

  1. Add 1" on your measure. For example: the measurement is 18", then you should choose 19" (18"+1"adjustment)
  2. Measure an older harness to find a fit for your dog. Measure an existing harness that is already sized to your dog's body
  3. Look at our Applicable Dog Breeds listing on product page and/or look at dog pictures below to get a good idea of where your pup fits in
