Lightweight Adjustable Mobility Rear Pet Dog Wheelchair Medium 20-39lb. I bought this from Doggon' Wheels 14 years ago for my English Cocker "Wesley", who had seriously strained his back. He weighed about 35 lbs. The device is adjustable, so it should fit many medium dogs including somewhat taller dogs.
Quite short might not work; a dachshund or a Corgi, for some examples, would be too short. Visit the Doggon' Wheels website for more information. It mentions a "rear support neoprene and fleece sling" that must have been added later, I didn't receive one. Wesley got worse; we never removed it from the box, I opened it today to take photos and make measurements.It was made in the US. More photos and measurements are possible; ask.
