For what its worth, I was in the same situation a couple of years ago. I had a 7-8 month old mini filly that bit, kicked, lunged with bared teeth, etc. I came to the forum thinking I was queen of the world (granted, I was very young...typical kid. LOL) and got my butt whooped HARD. I was basically told I was either going to get myself or my horse killed...or both. It was hard to suck it up and realize I was in a pickle and get help, but I did and that filly is now a beautifully behaved, 5 year old mini driving horse.
People in my town thought (and still think) I'm nutso for listening to a forum of strangers, but I'm living proof that these people know what they're talking about. I was actually able to influence my community regarding horse healthy and nutrition (around here everyone feeds sweet feed or all stock feed) and my mare is great now. She hasn't tried to kick or bite in two years. The forum has also helped me rehab a VERY sick, VERY thin filly who I otherwise wouldn't have known how to help.
I know we're strangers, and I know this is all new and weird to you, but try not to shut us out just yet. We're really not a bad group of people once you get to know us, and we all love our animals. I think that's why we react as quickly as we do.
