Bark+ wants to change the way we see dog pickup waste bags. To us its not just a bag. Our refill bags are designed to fit in our special dispensers - but will also fit in most common dispensers in the market. Our bag & dispenser combination makes tearing along the perforation a seamless process. Just one pull, one hand. You don't even have to look! The dispenser will also stop the preceding bag, getting it ready for your next use.
