My Tennessee Walker is sweet natured, but stubborn and headstrong, and very
jealous of other horses when I'm paying attention to them and not her! Once when I was roundpenning a mini while she was tied to the outside of the roundpen. She stepped onto the railroad ties surrounding the roundpen with her front legs and and put her head over the top and snorted and nickered and pawed, ect., ect. She backed off of them as soon as I came to her, and started up as soon as I left.
One funny thing she does is chase birds and dogs. One time I was doing groundwork with her in the roundpen and the guineas kept coming back into it for whatever reason. (Guineas aren't exactly blessed with brains.) Every time they came back in she was ON them suckers faster than a blink, with her ears flat back and head down. It was pretty funny. As soon as they left the roundpen she went right back to work.
Actually, one of my minis chased a dog, too. The dog was trying to herd her and the other minis, so she turned right around and chased that terrified dog back to it's pen. Imagine a tiny mini chasing a Blue Heeler! And that was actually a mean Heeler, too. No other horse had done that, and you get this teeny little gal chasing the ole bully across the place... hahahaha.
My TWH will lick my hand, too. I've let her drink pop out of my hands and since that first time she's licked instead of sniff or lip. I've grossed out a few people with it, hehe.
