My wife has had this mare since we met three years ago. (just got married last June). I think the mares about 5. My wife tells me "oh I've sent her off to be broke three times, and each time they came back and said she can't be broke". Well I love my wife, but sometimes she can embellish a little bit, and I'm not so sure of the caliber of "trainer" she sent her to. (Probably some young guy that said he could break her so she'd think he was tough, since she was single then). Anyway this girl kicked my wife's teeth out when she was in the stall fixing her water bucket. Apparently she'd be fine one day and let you ride her, and the next she will buck you off. She has been a 1200 lb dog since I've known my wife. No one rides her, no one has even tried (including myself) in three years.
Now I didn't grow up with horses, and I know next to nothing about them. But as I have been feeding and mending fences and cleaning up after one for three years now, I'd like to learn and start riding. Is a 5 yr old mare too old to change? Should I try to get a professional trainer to get her started and teach me? HELP! What should I do?
