standardbred mare lame ONLY at trot?
my friend has a standardbred mare, 6 years old I think, that only trots in the pasture. he's been riding her just fine at a 4-beat gait and a pace, and has never noticed any issues at all. I've never noticed anything while he's riding her either.
well, we saw her trot in the pasture the other day, and she is LAME. head-bobbing at the trot. she picked up a canter, totally sound. sound at a gallop. sound at a walk.
I'm 99% sure it's not an abscess. She was a little lame at a trot in the pasture about a month ago, but after a minute of her trotting around, she seemed fine. he gave her some time off, and she was never lame at all under saddle at a gait. this time it's the same hoof.
She was sound at a gait (and walk and canter) 3 or 4 days ago, but again, he never rides her at a trot.
any ideas? obviously she's not being ridden right now. we have NO decent vets here, so for any diagnostics she would have to go 3 hours away to LSU.
what's odd is that of her 5 gaits, she's only lame at one of them. I don't know much about gaited horses, but that doesn't seem right.
