I bought two mini donkeys a few weeks ago. Both were born in March 2010 and the little boy is extremely tiny. They were both not handled so are shy and have fuzzy coats. I noticed when I finally was able to touch them that they feel thin. I can feel back bone and hips but belly looks big. So I think it must be parasites since they have both gotten plenty of good hay and grain. I wormed them both with Equimax. I noticed yesterday the little boy is holding a back leg up and then he will alternate to the other leg holding up. It's very weird and something I've never seen before. To describe would be like a cat who gets his feet wet and picks them up. Anyway I checked both hooves, no warmth no sign of founder (which would affect front not back). No sign of any swelling or injury around legs. Any idea what this could be? When he walks doesn't appear to limp or walk strange. No sign of pain/discomfort. Before someone recommends vet, my horse vet isn't familiar with donkeys or miniatures and no other vet in this county can even do a pregnancy test on a miniature horse so I'm sure they are not knowledgeable on miniature donkeys.
