The other day my dog hurt his leg, the vet said it was a sprain. Nothing to be worried about, but he should stay off of it as much as possible to avoid stressing it. I figured a brace of some kind would help keep him from putting too much weight on it and stressing the joint. So I carefully measured his leg and printed him this lightweight brace! It fits his leg perfectly and it prevents the joint from moving. As a result, he barely puts any weight on that leg and it is healing very quickly! Obviously this may not fit your dogs leg, but I just wanted to show the community a way my 3d printer is helping out my dog :) For more ideas, please visit www.3dideaforum.com
