I was thinking, for all of you clever folk out there, I have a question. It concerns my maiden mare Sunny. I had her put to an Appaloosa stallion in June this year, prior to that, Sunny was calm, gentle and brilliant with other horses.
Right now, she has become aggressive to other mares, bitten Gracie twice and drawn blood. She stands mostly quiet, feeds well, but if another mare comes near, she will pin her ears back and lower her head, then launch herself at that horse. With me she is really odd! Nuzzles me to death, loves being brushed and when I come into the field, she is first to get to me! She has always been affectionate to me, and always been a kind horse, easy to do, and work with.
But there is something of a big change in her, she doesnt run around like she did, and almost seems to be another horse. When i handle her she is great as always.
This behavioural change, is it due to her being pregnant?
