Well, thanks to everyone for the information. I think the problem with Cashew (thats his name) is he was getting sick. When he was at the trainer his ears started running, never did that before. And when we brought him home that friday I noticed that he had like the green ( runny) poopie. (sorry). Now 3 weeks later he's gotten a snotty nose (green) mostly at night its worst. And mostly only on the left side. He also lost is apettite to eat, the first week home he wouldn't eat any hay, changed the bales, got new from a friend. Still wouldn't eat, but he was draining his water out everyday. I just thought it was due to being separeted from the other horses he was around. Now he's eating like he use too and drinking normally, but thats when the snotty nose showed up. No coughing or any other signs. Called the trainer and all her horses are fine. He did get into a fight with a stallion while he was there, and he didn't win. He came home with alot of cuts and scratches, but they all but heal up, the worst was on his neck. And its almost gone just alittle scab still there. I went ahead and started him on antibotic 6ml. but I just don't know how many times a day too give it too him. and my Vet is out of town for a week. Any thoughts, the trainer told me too start him on asafoetida and sliver clove and that should knock out any infection. Could it jus be allergies???? He in a great mood, he's wenning and storning and running around the field. So I don't know.
