This is a winner! We have two pit bulls, both of whom are around 60+ pounds each.  One of the dogs has had two leg surgeries, so we have to be careful not to have her jump too much.  We have a Toyota Rav4 and a Matrix and needed a ramp to get her in and out of the cars, as we take them with us around town and on trips.  These are car dogs -- they live for car trips, if only to the local store!
