I'm glad I could help! I'm sorry this has happened. It will take a while for the dead parts to shrivel up and fall off, but with a good amount of love and care he should make a nice recovery. As time goes on it'll become clearer just how much he will loose. I wish you luck and him a speedy recovery!After looking into it a bit more and the fact that its the tops of his feet and in his toes, not to bottoms. I think you might actually be right with the frostbite. I feel terrible now! Ive given him a relaxing toe soak with epsom salts and applied an antibiotic ointment. Hopefully he heals up
