Hi there. I agree with those who have posted. As for those feet in addition to absolutely clean dry stall you can pour Clorox on the cleaned out hoofs or soak them one at a time in some Clorox water. Vinegar is ok to use too but not as effective. Thrush- x is a good product to use. It is a green sticky liquid and provides some barrier to bacteria. How often do you worm your horse? Worms can take away any nutrition. You definitely need to feed grain. Use pellets with at least 10-12 percent protein but the key ingredient should be fat at about 6% to 8% fat. Your horse's teeth most likely need floating by an Equine dentist or a good vet. Your horse needs to get outside at least 4 hours per day. Check the fences or fence off a lot but get him outside. If you will listen to your friends on this website and do what is suggested you and your horse will feel and look a lot better.
