We were at a sporting competition (gaming for all you western riders :]) back in Januray. It was about 42 degrees, (Super hot!!!) and we did about 9 games twice each. The horses were cooled down and put away, then we found out we both made the flag spectacular, (the big final of the flag race, top 25 times) so we saddled back up and warmed up. We ran the race, and afterwards Sam said Pepper felt a bit stiff in his left fore. She walked him out and put him away for the night. The next morning, yep, he was lame. She didn't ride and we took him home. There were no cuts/marks, no sign of heat in the foot, no swelling anywhere on the leg, no soreness when we poked and prodded him. She gave him a few weeks off, but no change.
Vet came out, suggested it was an inflamed shoulder muscle.
She got the chiro out, who said he was out in the shoulder, so he adjusted him and said he should be ok to ride in a few days. That's what we did, he was a bit better, but would still put in lame steps at the trot. Chrio came out again, said the shoulder was resolved, so it had to be something else. Suggested putting shoes on him to try and rule out the foot.
Farrier came out and put shoes on him. Rode him the next day, STILL lame. Not as bad as he was, fine at walk and canter, but still lame steps in the trot.
Throughout there has been not heat, no swelling, no wounds...
Does anyone have any ideas? She doesn't have any other horse tor ide, so it's kind of lonely without her to ride with :[
