Here is the situation - 30 year old NSH mare diagnosed with mild cushings about 4 months ago and is currently on Pergolide. She has a stall with access to paddock and 1-2 acres of pasture. About 5-6 months ago her barn buddy left and she was alone for about a month then 2 new horses came to her barn (3 horses total). She shares the barn with these horses but she has her own pasture area. The head bobbing began about 2-3 weeks ago and she really bobs!
Any ideas as to why this has started? Any ideas how to stop it? Will the other horses learn this behavior?
