Dogs With Disabilities Special Product Needs

Having a dog with a specific disability can be extremely frustrating in finding products to meet very specific needs. Our Siberian Husky, Avalanche suffered a spinal cord injury a little over a year ago. He has made amazing progress and is now walking. The problem is that his right leg drags and therefore his nails drag and are worn down to where they bleed. His left leg is not bearing weight correctly and therefore he has one pad that is worn down to where it bleeds. I have tried a variety of dog shoes, but either they don't work very well, or he can wear out a pair in one 2-3 mile walk. I have been using infant human socks taped onto his leg with adhesive tape, but with the distance he is now walking he can wear out three socks per foot on one walk. That's three pairs of socks a day. Any ideas?
