Dog Water Intake Calculator
Calculate how much water your dog needs daily based on weight, activity level, temperature, and diet type. Keep your pup properly hydrated.
About This Calculator
Proper hydration is essential for your dog's health. The general rule is that dogs need approximately 50-60ml of water per kilogram of body weight per day. However, this baseline varies significantly based on activity level, environmental temperature, and diet type.
Dogs eating wet food (which contains about 70% moisture) need significantly less additional water than dogs on dry food diets. Active dogs and those in hot environments lose more water through panting and need increased intake. Dehydration can lead to serious health issues, so monitoring your dog's water consumption is an important part of pet care.

Frequently Asked Questions
How much water should a dog drink per day?
Dogs typically need 50-60ml per kg of body weight daily. A 20kg dog would need about 1,000-1,200ml (1 liter) per day. This increases with activity and heat.
What are signs of dehydration in dogs?
Signs include: dry gums, loss of skin elasticity (skin doesn't snap back when pinched), sunken eyes, lethargy, loss of appetite, and excessive panting. If you notice these symptoms, offer water immediately and consult a vet if severe.
Can dogs drink too much water?
Yes, excessive water intake (polydipsia) can indicate health issues like diabetes, kidney disease, or Cushing's disease. If your dog consistently drinks much more than calculated, consult your veterinarian.
