Hey, I have had my Belgian/QH gelding for a month and I have run into a problem. He stumbles and trips like crazy, mostly under saddle but will do it every now and then on the lead line. The first two or three times I rode him he was fine, then one day he was suddenly reallllllllly bad, he tripped every few steps and when I stopped him his back legs slide into his front and it spooked him into a canter. I tried him on different footing, same thing. I called our farrier and he trimmed the hooves but said there is nothing wrong there and he probably needs to just wake up more and stop shuffling. I would agree with him but he seems to trip more when he picks up his pace, like he is way less balanced at a posting trot than a jog. The barn manager says he is just fat and lazy and needs to move out more but I am scared if I pick up the pace anymore he is going to wind up hurting himself and/or face planting.
Any tips, have any of you encountered this before?
