 The wheelchair, I've seen several degenerative myelopathy German Shepherds that just are living their best life, even though they have to drag themselves around the house. If they have to go out, they pop them in the wheelchair and off they go. So I would definitely recommend putting a harness on them. I like the Help Em Up Harness. Help, H-E-L-P, M-E-M, Up, U-P. Help Em Up Harness is a very good one to help manage them in the house and manage them getting them in the wheelchair and stuff.
