We used a ramp with our older dogs to get them in and out of the car, and none liked it. Mulder was the worst - I think he was terrified of it. We basically forced him up it (after trying everything else we could), by having one of us on each side to keep him from jumping off (and hopefully feel more secure). I lured him with steak and pulled steadily on his collar while my husband pushed on his rear until he realized it was inevitable and he gave in and went up. at which point we threw a huge party and gave him the rest of the steak. It only took a couple times of that before he would go up on his own, but he was always a bit scared of it and would go up/down as fast as possible to get off of it quickly, which meant we really had to be ready to spot him in case he took a wrong step and started to fall off of it. I did feel bad about putting that much pressure on the old guy, but at 85lbs, I just couldn’t lift him all the way up into the car (I’m only 5’0), and he wouldn’t do the thing where they put their front legs up and you boost the rear, which would have been okay.
