Unless your dog is really adept at drinking from a stream from a water bottle, or you don't mind spilling a lot of the precious fluid on the ground, you want to be carrying the Ruffwear Bivy Dog Bowl on your canine treks. This collapsible bowl's seam-free, welded fabric technology creates a watertight seal to hold your pup's water during pit stops on the trail. Its stable shape and no-slip bottom allows for easy eating and drinking, and the bowl cleans up easily when you're done. The Bivy bowl collapses into a small package, so you can easily carry it in your backpack or even tuck it into your pooch's special doggy pack.
