Purse dogs rejoice! The original and BEST travel mug for dogs, now comes in a size that works for even the smallest pups! Public water bowls can contain harmful pathogens, travel water bowls are an inconvenience to use. Squeeze and water fills the bowl for your pup to drink, release and the remaining water returns to the bottle, not wasting a drop. Now, you can twist the lock in the center of the bowl to render a leak-tight seal, keeping your backpack dry when storing! Holds 15oz. Comes with a carabiner which can attach to a pack or your belt loop.
