These boots from PAWZ are made with a natural rubber and are 100% biodegradable. Each pack comes with 12 boots so when one wears out, you can toss it and replace easily. The thin rubber creates the most natural feeling for your dog with no clunky soles, padding or straps. Can be used to protect the paw pads from hot sidewalks, cold, ice and salt in the outside elements and inside, they can help prevent slipping on hard surface floors.
