I may put most of it in the fridge. It's old as dirt(1977 Sears Cold Spot) and a spare in the attached garage but still works despite it's age. As for Bubba, my 12 year old Corgi, I've tried two different carts, as they call them, and he refuses to budge in them. He just freezes. This past Summer I did manage to get him in the driveway where it was smooth and no bumps like the back yard and he did go up and down once with it but that's been it. Those carts were a bit over $300. I tried to no avail. Some take to them and some never do.
