Never be embarrassed again walking your dog and running out of poop bags! The new DRS-enabled dog-poop bag dispenser tracks how many rolls you have left. Once you're running low (1 or 2 rolls left), the dispenser makes a call and DRS sends you a replacement 10-roll pack. Choose your favorite supplier too! The dispenser works with a variety of different brands of bag-rolls. Hang the dispenser by your dog's leash and you'll never forget to bring a bag!
