I know people that have bought two different horses from auction that were obviously drugged. They don't seem to be related. Story is:
First, mare in early summer. Slightly over at the knee, but moved sound. Went well in the ring, very alert. The next day she was fine. Maybe slightly off on the left front. Went for a light ride and was very well behaved. Within 3 days of the sale she was horribly lame, on both fronts, worse on the left. Vet check confirmed, very bad trimming and over work had reeked havoc on both fronts. It started with heel pain, so she flexed her knees to lessen the pain, which over time shortened her tendons and gave her sore shoulders. The owner is in the process of slowly lowering her heels in hope of her eventually coming sound. She is extremely sweet, with an a+ attitude, Its such a shame.
Now last week a friend picked up a cute gelding. He moved PERFECT the day after, I tried him myself and he was great, w/t no favoring in the turns. The next day he was slightly off, but so slight it was hard to pinpoint the leg. The day after that he was obviously lame on the right front. Now he is very lame. His feet need a trim, but not horribly, and the angles are right. No swelling. Great attitude, super sweet, very broke.
What drug masks lameness perfectly, doesn't affect attitude or disposition and wears off in 3 days?
