I have owned my 15yr old Mare for nearly 11 years and she has always had a very sweet nature apart from a few days before her season. She has recently had a major change whereby one minute she is lovely the next she has her ears flat back and she bites us. She has also cracked Mum's cheek bone. She has also become unrideable. What could be wrong with her?
