Here's something cheaper>>>Leave him home.
I hope your joking....
I'm trying to figure out what I'm going to do with my 1 year old GS pup. The german shepherd dog's hips aren't too good as it is, and jumping in and out of a high vehicle doesn't make things any better. A cheaper solution would be one of those ramps that they sell on all of the pet websites. But then, you have to figure out where to put it when not in use... Let us know what you come up with. Congrats on your partner's retirement!
