I have a 3 year old Alpine doe that I can't figure out. She has been foaming at the mouth for a week or two now, no bloat, eats and drinks well, high milk production, about 7 weeks postpartum. Some days she has no foam, frequently just a touch about the lips, today it was dripping while she chewed her cud. No other does, just her. I have given baking soda, probiotics, wormed her with safeguard and ivermec and today cydectin. She has a large gash I have been treating for a week or so on her udder and she got a round of antibiotics for that, the wound seems to be improving. She has had a cdt vaccine. She also concerns me because she has been standing off to herself with back hunched and acts like movement is painful. Ideas?
