To start with let me give you some bg info. My horse in question is a 7 year old Thoroughbred (unraced) and I've owned him since March. He's always been somewhat aggressive, and doesn't enjoy brushing, socializing with other horses (would rather eat them) nor does he enjoy riding.
We've had his hocks injected because there being insufficient fluids in the joints, and now have him on a supplement and an monthly injection (basically that is all taken care of)
He is entirely un-rideable, when we do attempt, he tries to bite either leg, occasionally rears, and attempts bucking (stopped by a firm hand on the reins) a month of re-building after the injection we thought would help with what we though was behavioral issues (brattyness) Well facts are he's still in pain and extremely girthy. To avoid the expensive scoping (in my area averaging one thousand or more) We are putting him on a Ulcer treatment, as well as an antiacid to help the healing and prevent flareups, however I'm not entirely convinced this is the solution to it all (I hope I'm wrong with those suspicions)
Basically my long drawn out question is
A) have you had horses with Ulcers before, and how did they act prior to treatment?
B) What other solutions you might suggest to look into if this in fact isn't the answer to all our prayers.
I really do appreciate everything!
