I have a 60 lb goldendoodle who rides with me in the car on a regular basis. I'm new to the wrangler lifestyle and I'm nervous that he might jump (or fall) out of my new Jeep if the soft top is down. Does anyone have a harness they could recommend? I'd ideally like something I could hook to the roll bar so my dog could ride in the cargo area and not on the back seats. However I'm open to any suggestion so long as it keeps my best friend safely inside the Jeep. Thanks!
