Ruff Rollin Rear Support Dog Wheelchair good condition, no notable signs of use or wear. Clean, smoke free home. Please see photos for measurements and feel free to ask for more if needed. Suitable for x small dogs in my opinion. I have a larger shih-tzu and it's too small for him. The harness clips into the walker as shown in photos. The back leg Support harness detaches for wash. I know these retail for almost $500 but I'm hoping that this will go to a doggie in need and an owner who will appreciate. Feel free to ask questions!
