Maddie is an angel in the car, she just sits in the back and lays there or will look out the window when I stop. Rudy is a mad man, he is all over the place, which is very unsafe. Found a good seat belt that hooks to the harness on
www.petedge.com, that looks like it would be good, they can move around as long as you make the belt. Great price to $4.99 + shipping. It is called Guardian Gear # zw61107. I had order the small size but the strapes hook was to heavy I thought. The strap can just be hooked to your dogs own harness...............Cindy
