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.

Fits great on my larger frenchie. My little furball is odd in shape and after trying so many different harnesses this is by far the best. No more ill fitting harness.

This harness is great for easy walkers. The only downside is that with being short-legged, the leash is closer to the ground at her neck than on her back.

Bright colors and reflective stripes are also great additional features for overcast days. The price is affordable as well. This one works great!

I have a terrier mix and the problem is the strap around the front below their neck. The chest strap is fine it's just the other is not adjustable. This harness is unreliable and broke during our walk.
