I have a 9 year old Thoroughbred gelding; I've had him for over two years. I do not think he is off track, but he does have a lip tattoo.
He is rather thin. I mean, he has weight in his belly, and his hindquarters and shoulders are muscled, but he is very 'ribby' and his spine jutts out of his back (not horrible horrible, but enough to give a wedgie when bareback)
His teeth shouldn't be an issue, and he is on a regular worming schedule. His current diet is a mix of Purina Strategy and oats/molasses, and I just got some aloe vera juice for him to treat any ulcers that he may or may not (but probably does) have. He also gets very good hay, and is on pasture, but the pasture is very pathetic.
He is doesn't have any health issues, but I really want to get more weight on him. I know part of it will be exercising him more to build muscle on his top line.
So, my question is, what exercises do you recommend, and should I alter his diet any? I am unable to give him more pasture because where we board he is not allowed in with the other horses.
