Just lay it flat under you dog, wrap it around the and then clip the straps up around the neck of the legs. My dog is a 17lb bichon.

The straps and buckles look like they would be super durable, but a lot of th seams and stitching only gets the very edge of the straps. Couldn't even test it or try on because the straps were broken.

Product is a good quality product. Biting the neck part. The harness fit my dog well.

Did not fit my dog at all. Why are they even on the harness?
