Hi, My horses name is Sunny he is a 13 year old 16 hand Paint(Thoroughbred) cross. His back has this sort of bump towards the back that is getting very slowly worse and I am wondering if anyone knows why this bump is here. I trail ride him and do arena work and the tiniest bit of gaming (No jumping). He's barely ever lame except sometimes after a brand new par of shoes. He has front shoes on. He is pretty well balanced he knows how to engage the front end and hind end very well (So I don't think it has to do with him not engaging his body properly).
Also he eats lots, he is a thoroughbred so I can't feed him much alf without him becoming very high but his weight is weird he eats two and a half flacks of alf mix twice a day and he has a big belly that gets bigger if he's getting to much feed but his ribs are always showing and his back bone always looks weird. Like it's sicking up way to far or his belly is almost hanging... He's worked very often, he lives on a luxury ranch. The feed is high quality. He has been wormed three times this year. He is up to date on his shots.
Here are two photos one that shows how much his ribs show and the bump in his back and another that shows his conformation better. (ope that the nicer photo is from last year, so the bump is smaller)
Your thoughts are very helpful!!
