THE QUICK ANSWER
A dog harness should be selected from actual measurements and checked in movement. Breed names and body weight alone are not a reliable size specification. For a private-label range, ask for a measurement chart and review strap position, adjustment range and fit across the intended sizes.
A QUESTION FROM THE COMMUNITY
“If my dog's harness fits everywhere else, but is sitting in his arm pits and rubbing, is it too small?”
Why does harness fit come up so often?
The linked Reddit discussion describes rubbing around the front legs. It is an individual experience, not proof that every harness of that type will cause rubbing. It does reveal a useful development question: does the pattern fit different chest and neck proportions?
How should a dog be measured?
Ruffwear’s measuring guide starts with girth around the widest part of the chest behind the front legs. Use the chart for the particular harness being considered; size labels are not interchangeable between brands.
What should a sample review include?
Check where the straps sit when the dog stands, turns and walks. Record adjustment range, edge finishing and whether the leash attachment changes the position of the harness. A fitting video can help explain adjustments more clearly than a single product photo.
What should a brand put on the product page?
Publish a product-specific size chart in inches and centimeters, a measuring illustration or video, and clear fitting instructions. Do not promise a universal fit or call a walking harness crash-tested without applicable evidence. Stop using gear that irritates or injures a pet and seek veterinary advice for skin damage.
