So, I have a 4 year old I am trying to put miles and muscles on. I increased his grain about 3 weeks ago to 3 scoops of grain morning and evening. About a week ago, I notice that he is looking better, a bit fitter, a bit more muscle and a whole lot more energy. He is behaving badly and I am wondering if he is just feeling to hot to handle. I am wondering if this is a lack of training issue or a grain issue. He is a bit of a pushy horse but I have pretty well kept that in check for the last year. This week he has been crow hopping under saddle, trying to take off in the ring, trying to paw (not a strike but more like a testing the waters move) at me on the ground (which resulted in a come to jesus moment). None of these tactics have been successful and so he is trying new things in my opinion.
Is this a phase? In your opinions, is this the result of a lack of ground manners or a young horse with so much energy he does not know what to do with himself? I am planning on talking to his owner (a vet) about cutting him down to two scoops of grain. He is on a scoop of LS (high fat grain extruded grain) and two scoops of endurance. He also get hay and there is some grass in his pasture. I am working with a trainer with him; however, our next lesson is not until Monday.
