Y'all have pretty much confirmed what I was thinking but here are the pictures I said I would try to get! He still needs a lot more muscle, but he is looking great compared to what he was. I am hoping by the middle of the fall we will have some real progress :)
Excuse the semi-horrible quality and Drifter's alien eyes. It was dark so I was using the flash. And I feel like no picture I ever post of him does his justice. He is so not photogenic. He looks a lot better in person! Hahaha
Your horses body looks exactly like mine...except yours has a slightly better topline. I am working on building muscle as I believe that's what he needs. And as other people said, that's what your horse needs.
