My buck was laying down with droopy ears, when I got him up he had very unstable shaky legs he went off feed although I could get him to eat a few crackers and leaves. I hit him with penicillin for 10 days and probiotics. At 3 days he started to show improvement. Did a pretty good recovery but started to scour. Stool sample originally had stomach worms. Wormed with Panacure and did follow up a couple weeks later with Ivomech inj in water. 2nd stool sample was clean. Checked for Johnnies disease was clear. Now 2 months later he seems to be doing well but hunches his back just a little, his hair coat seems a little void of his main guard hairs and his hair kind of stands on end. And he still has loose stools with some crap on his butt and tail . Any ideas??
