The only caution flag that came up is his right hock has fluid around it. He either hit it against a wall in his stall, or did something to it if he layed down (underneath the shavings in concrete)
He's not lame on it or anything, but it's there.
I am definitely going to want to get a pre-purchase exam on him, but I want to ride him more and see how he is on different days and stuff like that before I decide that I really do want to buy him.
He also doesn't get a lot of turnout so he's in his stall pretty much all the time.
Could him being confined prevent the fluid from going down?
What long term side effects would/could there be? Is there anything else I should be concerned about?
