Enough Space for Snacks and Pet Toys: The main snack bag compartment is large enough to accommodate most essentials, such as dog snacks, clickers, toys, etc. Size: 40 * 14.5cm Hidden Bottle Holder: Open the zipper pocket on the left to release the bottle holder (bottles not included), which can hold up to 750ml bottles. When you don’t need it, just close your pocket to hide it. Convenient Handling of Dog Droppings: A small but very useful improvement has been made to the dog food bag, adding a small metal hook to carry the used trash bag hands-free. There is also a dog poop bag dispenser for the new poop bags. Other functions: Additional D-rings for dog leashes or other accessories. With reflective tape on the front, you can walk the dog at night or early in the morning.
