Use Your Flat to help your dog, the environment, and open your beer

Cycle Dog repurposes flat tubes into pet products. They make collars and leashes out of used bicycle tires/ flat tubes. They accept all sizes of tubes from individuals and bicycle shops. My favorite product is the green reflective bottle opener collar. See it in use on my dog below.
