How the Pet Daily Water Intake Calculator works
A common estimate is about 60 ml of water per kg of body weight per day for dogs and 50 ml per kg for cats. The total includes moisture from food, so a pet eating wet food drinks less from the bowl. Hot weather, exercise, pregnancy, and nursing raise the need. A sudden jump in thirst can signal illness, so call your vet if it lasts. Example: A 10 kg dog needs about 600 ml a day, which is 2.5 cups.
