These patent-pending "No-Stink" collars are created from a special blend of synthetic polymers that won't absorb moisture, retain dirt, or harbor bacteria. And that's great news since, let's face it, if it's wet, muddy or stinky, your dog will find it. And when they do, just rinse the collar under a bit of water and you're ready for the next adventure!
