what size harness does my dog need?
please ... measure your dog for accurate harness sizing ...
The UdogU Easy On Harness is designed specially for smaller dogs, to avoid the trachea problems that can arise from stubborn pulling on a collar. Our harness fits dogs from under 3 lbs. up to approximately 45 lbs.
Like all great attire, the UdogU Easy-On Harness depends on accurate measurements for the perfect fit. Different breeds have different "figure profiles", so weight alone may not tell you which size you need. Slender breeds (dachshunds, for example) will need a smaller size than stocky breeds (such as pugs) at the same weight. Your dog's ribcage measurement is the best guide to harness size.
Please measure around your dog's ribcage just behind her front legs, as shown in the photo, then refer to our Harness Sizing chart. You may find that two different sizes will fit your dog. Normally, the best size to select will be the smaller of the two sizes. But don't worry - with our Harness Fit Guarantee, even if you select the wrong size, we'll exchange it for you.

New Harness Size Exchange Policy
Due to the large number of harnesses that are returned to us for a larger size, we have changed our Harness Exchange Policy. If you have ordered the wrong size, please send the unused harness back to us within 30 days, and we will refund the charge for the harness and any associated sales tax. You are welcome to place a new order for the correct size.
Harness Sizing
Please measure your pet carefully, and base the size on the ribcage measurement, not the weight. It will save you from exchanging the harness. We find that most "teacup" dogs fit our Teacup Plus harnesses. If you like, please call so we can discuss the best harness size for your dog.
