I have a 10 year old doe - father is a fainter, mother a grade pygmy. I've noticed recently that her hair is a little scruffy but otherwise nothing different in behavior. This morning she was shivering and yes, it was cold today in PA. But we've had some other cold mornings and no one else was shivering. then I noticed that a younger doe was harassing her and head butting her. She was butting back but she seemed stiff, almost like the fainting gene was "popping out" after all these years. Later, she was still walking kind of stiff and seemed to want to get away from the others. Not sure if it's polio of listeriosis (never did figure out what the main difference is) but have thiamine here, so gave her 2 cc. She probably weighs about 65 pounds. Does that sound the right dosage? She already seemed more stable on her feet. Also put an insulated jacket on her and now have her separated from the others. any other thoughts?
