The Attitudz Bones Waterproof Dog Collar is a great combination of style and function. It is made with Biothane material, which makes it not only water-proof, but also stink proof and soil resistant. It is an all weather collar that is easy to clean and durable. The matte black D-ring makes it easy to adjust a leash to, and the Kwik Klip buckle makes for easy on and off. It is adjustable for a custom fit.
