I went to Home Depot and bought a piece of carpet runner to go on top so that stuff wouldn't slide. Was cheap, too, at less than $10.toybox said:Not only is it inconvenient if you have a dog, my dog at least, can not get a grip on the hard surface of the DD cargo thing. He slides around on it and I can tell it was stressfull for him. I now put a rubber mat over top of it and he is fine.
Glad that your dog has a grip now -- don't want him to slide in his truck that he lets you drive from time to time.
