I was able to adjust the chest straps enough for snug fit but there was no way to adjust the harness around the front to make it snug enough her legs would not slip out.
The harness is easy to put on and take off. I'm glad I ordered one.
It's actually the design of the seat clip that attaches to the harness that I dislike. It's plastic and being plastic it is difficult to depress prong of the clip, especially with the double-lock feature, to click the harness into the seat cushion to secure the dog. It is especially difficult to open when the plastic is cold and I am wearing gloves. A metal trigger snap would be much easier to work.
The dogs like them too! No stress to put them on the dogs.

my little 4 pound she just got her new petite harness for use with her pupsaver car seat and it fits perfectly! She had outgrown the mini petite I had gotten for her as a puppy and I feel so much safer always having her in her pupsaver car seat with her pupsaver harness. Thanks pupsaver!
