Dog Water Intake Calculator — FAQ
How much water should my dog drink?
Roughly 50–60 ml per kg of body weight per day. A 10 kg dog needs about 500–600 ml. More in heat or after exercise.
When is my dog drinking too much or too little?
A sudden, sustained change in thirst — much more or much less — can signal a health issue. Check with your vet.
Does food affect water needs?
Yes — dogs on wet/raw diets drink less; kibble-fed dogs drink more. The estimate assumes a typical diet.
Is this veterinary advice?
No — it’s a general estimate. Consult your vet for health concerns.
