Yes, we got him back into shape. BJ is a 30 year old 16hh QH gelding. The first picture was not even the worst and the 2nd picture was mid summer--he has even more muscle now. He has only 7 teeth left so gets a mash 3-4 times a day.
My girls got him as their own personal therapeutic riding horse.
After some groceries they started riding him for 5 minutes at a time at a walk. By mid summer he was doing 1 hour easy trail rides with some brief bits of trotting and loping in there. He would still jump if I let him (or my girls) try it.
This is the one that gave us an ulcer scare 2 weeks ago but he seems to be on the mend now and the girls are back to riding him lightly again.
