Yep, we build them for the big boys too! Kona is a 180 lb St Bernard. We were able to measure and fit this dog wheelchair right here in Bozeman! He was a gentle giant. Kona was able to feel great relief to get weight off of his aging hips. But I think his human mom felt the biggest relief, as Kona was almost paralyzed in the rear end and was unable to help at all!
