Hey congradulations.
He doesn't look to be in bad shape. Course a picture is only a picture. Seems to be a big round boy, well fed.
Now I am going to pretend that I can give advice.
Hooves. My horse has/had cracked hooves. Farrier says they are superficial, unsightly, but not affecting his health at all. His right fore, was cracked all the way up to the coronary band, the other three to varying degrees. I started him on a regimen of hoof supplement. Originally using Farrier's Fomula, but that stuff is "spendy". So after comparing additives and protien content, plus consulting the vet and farrier, I switched to Dumor Hoof Supplement, about 1/3 the cost. Both were in agreement that healthy hoof growth was what he needed to get the cracks grown out. Also we went fram a 6 week to a 4 week farrier visit interval, because of the accelerated growth. Initially as the cracks grew out his hooves looked even worse, big chunks breaking off the leading edges, now most of that is gone. His has huge amounts of healthy hoof growth, but we are still looking at another 6 months before in my opinion he has healthy hoof top to bottom. Both the vet and the farrier agree that his hoof problems began with a very poor diet.
I am not pretending that I can diagnose a cracked hoof via the internet, Lord Knows, I couldn't diagnose it if it hit me in the head. What I am saying is maybe it won't be necessary for him to get shoes.
