My puppy got to my new crocs. They are the kind with a solid top and vents on the side, I wear them to work. They are black, if that helps. The little man chewed little stab-wounds in the tops down near the toes. Is there any way to resurface or sort of smooth them out without ruining them, or is there a (somewhat) easy way to add a toe piece to them that would camouflage the damage?
