My old gelding is dead broke and never gave a single problem at all , I mean not ever has he acted up or anything . Rode a month ago and he was great , then the next week and still going he acts stupid and like he forgot everything , doesn't want to leave the barn or other horses , He has never been barn or buddy sour at all , kind of a loaner . I tried leading him down the road and getting on out of barn site and he just turns and goes back no matter what even with spurs . I am at witts end with him as I have tried everything I can think of as to what might be wrong .
Any ideas what to do or what could be wrong would help , Thanks
