I had Amber's shots and coggins done yesterday, and I had the vet watch her on the lunge and do a general exam (no flexions). She thinks Amber has some hind end lameness.
She gave us bute, told me to give her 1g 2x a day and see if she improved in her movement in the hind end and if she did it probably indicated lameness. She recommended us to another vet for Xrays because that vet has a more advanced Xray machine.
I've had multiple opinions on Amber's toe dragging. Amber's kinesiologist found no lameness, and my trainer though she was moving fine aside from that. Her previous vet gave her a hock injection, which didn't make any difference, and she recommended I not get Xrays because she said she'd still end up injecting the hock.
Amber drags both, but one side more. However she doesn't act like she's in pain under saddle. She's willing to go forward and is very relaxed. She doesn't favor any side, and never misses a lead. She gets auto changes over the small courses we've been doing (although we've only been jumping about once a week).
Obviously I'm not expecting to get a diagnosis here on the forum, but while we're playing the waiting game with this "bute test" and waiting to get her Xrays, I was hoping to get some ideas. The vet said it could be stifles, hocks, possibly in her hips. I'm thinking more towards stifles. She doesn't stab her toes, she just doesn't really lift them when she goes forward. And being that the hock injection didn't do anything, I can't help but think it's something else.
