Hey guys, i'm asking this question for a friend. She has a 7yr old tb gelding who went out on a lease about 2 months ago. They recently ended the lease and brought him back home due to a bucking problem that has suddenly started. Being that he has never bucked before, the only thing anyone can think of is that he is in pain somewhere. They checked his tack, tested him for lyme, had back x-rays done and everything came back clear.
Any ideas on why this horse would suddenly be bucking whenever someone rides him??
As always! Thanks in advance!
