I am currently bottle raising a Saanen cross that has had weak legs from birth but got around fine. However, he's slowly gotten worse. First his front legs contracted over and he walked on his knees. Now it has progressed to him falling over and being unable to right himself. His back legs are now stiffening out straight. He is very frustrated and flails around constantly. He has been given Bose shots, Vitamin E, Thiamine(in case of polio) and Nutridrench in his replacer. He receives physical therapy multiple times a day. He has had his front legs splinted and I "walk" him around with a towel around his middle trying to get him to use his legs. I'm out of options and I can't seem to find anything that matches his symptoms because other then the leg problems he is growing well with a healthy appetite. Please help!
