I'm still buried in a heap of homework, but I had to run out to the barn this morning to hold Izzy so she could have her feet done. She's still happy and barefoot with lovely feet.
While out there, I talked to two different horse people whose opinions I value about Izzy's contentiousness lately. I literally cannot walk away from her when she's tied up and there's another horse around. She will lunge at and attack them. She's pretty good about not doing it under saddle, but I'm careful not to get too close to anyone.
Both of them pointed to it as an example of insecurity on Izzy's side. She is in some way incapacitated and feels threatened by the other horse, so she attacks in order to gain safety. One of the people who mentioned this was the farrier/trimmer. She was working on Izzy in the pasture, so Izzy could eat breakfast while having her feet done. Her pasture mate tried to approach and Izzy pinned her ears. Before the situation went any farther, Toni (the trimmer) approached the other horse with an aggressive posture and told her to go away. She did,Izzy relaxed, and all went well.
I'm intrigued. I'm not one who usually speaks up for myself on other people's property. If Izzy pinned her ears at another horse while I was leading her, I'd be more inclined to discipline Izzy than approach the other horse because I feel the other horse isn't mine to control. This method makes sense, however. My only trouble is trying to figure out how to make Izzy comfortable at the hitching post so we can circumvent her lunging at other horses. Any ideas?
