I have an Andalusian cross who I think broke something up in her hip or dislocated her right leg. Both of her feet have full use but she has trouble keeping her right leg under her and protests when I put it under her. Her left leg works just fine. I don't think it's Marek's disease she also won't sit up, she lays to one side preferably her injured side. What should I do? I have been giving her meloxicam once a day and attempted to wrap it up against her body but she pulls it out of the sling. She moves around a little bit during the day but never stands up or attempts to. She also doesn't correct herself if you stand her up and slowly let her go she only falls on her face or to her side.
