Tebow, now 7.5 months, weighed 46.8 lbs today. No wonder it's become a struggle to lift him into the back of the SUV! (I should rename him "Butterball".) I almost dropped him today trying to lift him up. I've read reviews on some foldable ramps with the harsh sandpaper on the ramp injuring paws. The folding PetSafe stairs got pretty good reviews though some dogs are scared of them as major complaint. The bumper of the SUV is 25" up and it appears that when folded, the PetSafe stairs might fit next to his crate in the back. I would really appreciate any recommendations. (I've already started lifting weights and doing pushups just in case...)
