My blue roan Edward gets horrible fur balls matted with mud between his toes. I dry his feet everytime he comes in from outside but still these fur balls appear. My difficulty is that he won't let me cut them out. He gets really stressed. My vet gave him some knock-out pills to calm him down but they didn't work so as a last resort he had to have a general anathestic. I don't like this approach at all - does anyone else have the same problem? Is there a solution?
