Hi I am new mini owner. I have a gelding that is 38", and I am soon getting a weanling (in Oct.) My new guy is only using three legs, he was sick with joint ill and it left his hock fused together. I am looking to get him a vitamin and some kind of bone supplement. Does any one have any suggestions on either one of these? He gets around really well right now, but I think he needs a little help with some supplements. I would really apreciate any help any one can give me.
