PetSafe has thought of everything with this half ramp! I have a smaller car that my older dog has trouble getting into. I didn't want a big ramp that was heavy and couldn't fit in my trunk. I opted for the half ramp which fits perfectly in my trunk! It's lightweight, yet sturdy and I simply set it up to my open passenger door and my doggo strolls out! So much better than having to pick him up and struggle with getting him into the car. I highly recommend the half ramp for mini vans and lower to the ground SUVS! The ramp itself has a non slip barrier so when your fur baby goes up and down they don't slip!
