My friends dog Osi is still not getting better. Osi is a big - loving and athletic pit mix who is about 8 years old. She has been taken to 3 different vets, and put on 4 different pills. Symptoms are constant pacing, panting, shaking/trembling, crying and avoiding contact... Doesn't really want to eat but will if she's hungry enough so she's losing quite a bit of weight. Hoping anyone has had similar experience? It's heartbreaking. Vets have not yet been able to pinpoint what is going on. She may have suffered an injury playing in the snow. If anyone has had similar experience and would offer up an opinion or ideas for them to look into it could be helpful.
