So last Saturday I started bringing Mitch back into work (after me being thrown severley by him in february) and he was really good, I rode him lightly every day for 3 days, on the 3rd we had a small canter and he was fine, on the Tuesday (4th day) I got on him and he seemed off at the walk, so I got off, checked all his hooves, picked them out again and sent him walking and trotting on the lunge... Sure enough he was limping.
So I haven't ridden him since then, hoping it was just a stone bruise or something minor, he had a little bit of heat in the left front hoof the next day, but none since then. His lameness is just getting worse though, it was only slight on tuesday and now he struggles to even walk let alone trot in the paddock, hence why I haven't ridden.
It was quite hard to distinguish which hoof he was sore in at first and I was worried he may have hurt his tendon again (previous bowed tendon in right front) but after this morning on the lead it's definitely the left front.
There's no stones in the paddock he's in (that I've seen) and he's in on his own.
