We all have walked a dog and looked down to see our dog with their tongue hanging out. You try to give the dog water with a water bottle but you are just dripping water into the dogs mouth and they are still very thirsty. A dog needs proper full extension of their tongue to get proper water consumption. Flask Dog has a dog bowl attached, so your dog can drink like a dog. Since the dog bowl is attached to the bottom of the water bottle it will never touch the part you drink from. So you only need to take one bottle out on your walk and you can share flask dog with out the dog germs.
