You should share everything with your dog. Even your water bottle. Wait - hear us out on this. This 24-ounce Blue Gourd Water Bottle is perfect for people who want to pack light, stay hydrated, and treat their dog right. The top slides open - you know what to do - but it also has a plastic cup that snaps onto the bottom. You drink from the top, your dog drinks from the bottom, everybody's spit stays where it belongs.
