Very secure

I have a chiweenie (length 12 in, girth 15 in, neck 11 in, 8 lbs) and I bought the XXS. Finally she has a car harness that I feel would actually keep her safe. It isn't a hassle to put on and she doesn't fight me putting it on. I haven't gotten in an accident, but its a heavy duty harness. I am very happy with it.

Wanted more of a restraint

Love the design kinda difficult to figure out even with the video. Still using my old one from Sleepy pod. Need to play with it more to figure it out.

dog harness for car travel

Product was exactly as described, and of good quality. Sizing true to form, a gift for my son's large Labrador and he loved it.

Great Roadtrip buddy

Keeps Duke safe on our long road trips. He is comfortable and can actually move around the seat more than I thought he would be able to.
