Gordon's foot

Gordon's foot is not healing very well and i can see pus forming at the wound again. I've cleaned it. I guess dirt must have gotten into the wound. I have to apply a natural antibiotic to it all the time to keep it clean and also help it to heal faster. It's bandaged loosely all the time so that dirt cant get onto the wound. I hope it heals soon. Each i have to squeeze the pus out, he screams the house down. Hurts me more than it does him.
