Odd behavior, please help!
We have an older morgan horse, i think she's about 20. Anyway she's been acting incredibly weird lately. She has had a serious change in behavior, and her coat is very nappy and thick, she is also sweating all the time. As far as her behavior goes, she is becoming very aggressive towards the mini horses we have at the barn. She gets aggressive with people if you try and halter her, or if you go near her after being with the minis. Only thought we have is cushings but after reading some of the symptoms on line I'm not too sure. Does any one have any ideas? Any input would be greatly appreciated!!!
