According to PetPlace.com, "Dogs generally need more water compared to their body weight than their human companions do. A rule of thumb suggests that dogs should drink a fluid ounce of liquid for each pound of body weight. As with people, needs will depend on various factors. Active dogs and pups who live in hot climates, for example, may need extra water each day."
That's why it's important to have fresh water always available for your dog, at home, on hikes and when you travel. PetPlace has published a comprehensive article about this subject that includes:
