What a wench. :-) I can't believe that she tried to bite ecurbh, and she looks pretty pissy in that photo too! She needs some serious boot camp. Didn't you have similar issues with her "crankiness" (That's the polite word I'd like to use) when you got her?
I believe she's fallen into the habit of regarding Hair and Ecurbh as "The Help", and believes herself to be Ivana Trump. Boy, has she got another thought coming! ;o)
Yeah - worse... ;~D
Remember, she was bottlefed... and had obviously been allowed to walk right over the top of people.
But she's not hard to correct. She just tries mischief. As soon as I had a rope around her neck, she was docile as a lamb. She'll do stuff like pin her ears and stomp when we're putting her blanket around her belly, but if you say 'HEY!" and slap her, she stands nice.
She'd be a good horse for those clinic cowboys to use as an example horse. She'll do the bad thing, and respond to the first correction :~D She's bad, but soft... you don't have to break something over her to correct her.
