Wagon or pet wheelchair (WLA/Westwood (But will drive!))

Sweet Lucky Lefty broke his paw and isn't supposed to be walking down the long hallway we need to walk down to take him outside multiple times a day.

Anyone have a wagon or pet wheels Lefty can borrow? Luggage cart? Or something else we can use to take him in and out without bearing weight on that paw? Open to creative solutions. We need it for maybe 1 to 2 months.

Thank you!
