Step 8: Bring in the patient, Strap him in, and Turn him loose
The video is some of Merlin's first few steps. He's taken quite nicely to it, although he's still pretty weak, so he doesn't stay out for long. He still tries to use his hind legs, so we left them unsupported. If your animal is paralyzed or there is some other reason, you may want to cut the frame rails longer to give a place to support the legs, or even add extra casters (turn able wheels) up front or behind to support the extra weight.
Now he can get out and play with the rest of the family.
