Im curious to what everyone does to keep their dogs safe in the car. I recently bought 3 seatbelts that connect to my dogs harness' with one end a seat belt clip and the other a regular clasp to attach to the harness. Its adjustable and works well but they are taking some time to get used to it. I had a "hammock" in the back, the Kurgo one, but it shifted and my one pup liked to climb under it and lay behind my seat and the other one would jump over it into the front while I was driving. Not safe. What do you use?
