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.

Makes walking 2 dobermans much easier using the front clip. The connectors feel pretty sturdy and the material is tough and durable. Works for my 70 pound staffy mix who is super strong and can pull hard on the leash.
