Overall worst experience involving a horse?
You could've been on the horse, watching another person, on the ground with your horse, lunging your horse, ect.. but what was the worst thing you'ved watched/experience dealing with a horse?
This summer, my lesson was riding in the small ring. A friend of mine, Amelia, was riding Freddie. He was a huge appaloosa gelding, six years old, VERY clutzy, and fast as could be. She was cantering him around a corner and all of a sudden, he slipped to the side.
He came crashing down adn when Amelia stood up from her fall, she walked directly away from him! Freddie was her baby and she would've normally gone to him right away.. it wasn't like he'd gone anywhere, he stood up right next to her. Our instructor told her to lie down and almost immediatly, she collasped. I was freaking out- we were pretty close and she loved horses.. all I could think about was 1) she was hurt badly and 2) she might never want to ride again.
Amazingly, another instructor came to check out the situation and asked her if she could walk. She did, and a few minutes later mounted up on Freddie again. She even cantered and jumped the same day!
