The non-slip collapsible dog bowl is made for beach days! The bowls include a matching rubber ring to place on a water bottle and a carabiner to clip it on to a backpack, purse, dog travel crate, dog leash and more! When expanded, the bowl holds up to 12 fluid ounces of water or 1.5 cups of dog food. Made with high quality flexible food-grade silicone, you can rest assured that when your pet is enjoying food or water from one of our bowls they're completely safe from toxins, and so are you.
