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.

Love the blinking glow in the dark leash! I am lite up and so are the dogs i walk with. Holds charge well.

Was great first 2 months. Tried charging them again and had same problem. Now the other three are super-dim even on a full charge. The lights have a serious defect.
