If you let your dog roam freely in the car as you drive, you might want to consider getting a seat belt leash. It’s a short leash that attaches to the seat belt buckle. This will help with any issues of your dog trying to crawl into your lap or move into the front seat while you’re driving. It will also keep your dog safe from flying through the windshield should you get into an accident. We got ours at Pet Supplies Plus in Turlock, CA.
