Well, we took Mench for another walk and this time it was a long one. We played in the cul-de-sac and I don't know how it happend but he has dime size sores on both his back feet. I have soaked them in Epsom salt and tried to bandage them but he keeps chewing and licking at them. I have given him aspirin too. I feel horrible. I didn't even realize it until we got home and there was blood all over the floor. Any other advice?
