17 Year old morgan cross gelding in River John, Nova Scotia

Looking for a home for my old guy. He is bay in color, approx 14.3hh. Great to work with on the ground and great barn manners. He is green but has lots of miles on him (quiet) was used as beginner lung-line horse. Has some health issues which require an experienced horse home. He is now retired as we cannot determine his problem. (Colics after any amount of work/stress). has been vet-checked, blood tests, whole nine yards and has always come up with nothing. Has been treated for ulcers, urinary infections, etc etc. He is now on a new diet to determine if bladder stones may be the issue. I truely hate to see him go but must rehome him asap. If you are experienced and want to dedicate your time to a sweet ole fella, than email me for information. No kids please.
