I have a 15.2hh quarter horse that has been impossible to put weight onto since I got him 3 years ago. He has regular worming and dental care. He is on pasture and gets fed twice a day as well as grass hay. I've tried a few different diets. Atm he gets economix, copra and molo mix, with vegetable oil and apple cider. He has always been thin. I'm beginning to suspect ulcers? How do I found out if that's the case? He often has a dull coat too, which I know is a sign of ulcers. Is it possible he's had ulcers since I got him? He's 16.
Thanks! I appreciate any advice regarding food types or ulcers! He's currently a body condition score of about 2, maybe even 1.5
