HELP! I know ponies are brats...but this is crazy!
I typically pride myself on being a knowledgeable horse person, but I'm at a complete loss and need to pick the brains of other knowledgeable horse people.
I recently bought a pony that seemed great. I had planned to start a lesson program in my town, and was going to use this pony to get it off the ground. I bought a 6yo., 12.2, Dartmoor gelding 10 days ago and he's been a nightmare.
Some of his history...His previous owner had him stalled for FOUR months because she didn't have any turnout. (...don't get me started on that...) She bought him for her three year old daughter from a lesson barn and her daughter rode him on a lunge line (I've seen video as proof). They're selling him because they didn't have any time for him.
Anyway...I bought him and brought him to a little farmette (literally 5 stalls in an oversized run in shed) with a paddock and a huge field. There are 2 mares, another gelding, and a mini mare. Upon coming to the farmette, he was great for the first 24 hours. We had him turned out in a paddock by himself and he was great. He stood for grooming, was still the pokey little pony I had thought I bought. The next day, I go out to lunge him and he's turned into the devil wanna-be stud. He broke through the fence in the paddock to get to the mixed herd. He tried to mount a 15 yo arthritic mare who couldn't run away and ran the other mare so hard the owners of the farm thought they broke out of the field. He's rolling around in the mares urine/poop and herding her around the field. He was overly agressive to the gelding (pawing and kicking/biting) to the point that while the gelding was stalled, this pony came up to his gate, pawed at him and got his leg stuck in the gate. He tried to kick at the owners mom when she tried to lead him away from the younger mares stall. Even worse, he bolts away from me while being lunged to get back to this mares stall.
The next day, I hop on his back (at 5'4 it was a joke), and he's the quiet, pokey pony that he was when we bought him. Popped him over a cross rail, W/T/C him and nothing went wrong.
A couple days go by and I go out again, and he's stopped caring about the mares, is still somewhat annoyed by the gelding but not near the extent of the beginning, but now bolting off is his new favorite thing to do.
I can lunge him (with or without lunge whip) and he bolts off. He has broken my finger, kicked at me, charged me to get to the in gate and run around the ring like a wild pony. If you crouch down, he'll trot right towards you, and once you take a hold of the lunge line again, he'll bolt off. Every once in a while he'll do 2-3 rounds of good walk/trot, but if you give him more than 6' of lunge line, he tries to bolt off again. If he does this enough, he'll become agressive towards the gelding again once he gets back to the barn. My husband has lunged him and because he's bigger/stronger than me, he's been more successful at not letting go of the lunge line, but he still tries to bolt.
I've had him vetted...no cryptorchid but haven't had his testosterone tested yet. I obviously can't put beginner kids on him. I don't trust him and can't be lunging him with a kid riding, and still waiting for him to bolt off.
Has anyone dealt with an overly bratty wanna-be stud?! This is crazy and I'm at a loss!!
