MIEventer, no I never actually got him scoped. Unlike Nelson, Puck's a easy going as they come. He had just been unwillinging to work or even move much for about 6 weeks. It was around the same time that his best buddy and pasture mate left and the BO refused to put him with another horse, so I know he was stressed out. We kind of got to the ulcer diagnosis through ruling out everything else. I could get him scoped post treatment, but I have a feeling it would just show me a healthy stomach. Next week we're moving to a new barn where he'll have buddies again, a diet heavy in hay and forage and access to plenty of trail riding which he loves. If there were ulcers before, I doubt they'll return under those circumstances.
I've already been through EPM and a stage 2 heart murmer with my one and only horse, so yeah, I am a little on edge if he so much as coughs. I've been reading about natural preventive remedies for ulcers. It looks like bananas are very good for coating the tummy. I think I'll see if Puck's a banana fan and then try to stop worrying so much.
