Water is the single most important nutrient for your dog — making up about 60–70% of an adult dog's body weight. It is involved in virtually every biological process: digestion, circulation, temperature regulation, waste removal, and joint lubrication. Dogs on kibble-only diets get very little moisture from their food (typically 6–10% water), while dogs eating fresh or wet food get a significant portion of their daily water from meals. Adequate hydration supports kidney function, helps prevent urinary tract issues, and keeps skin and coat healthy.
A standard water bowl holds about 500ml — a medium dog (10–25kg) needs roughly 50–70ml of water per kilogram of body weight per day, which works out to approximately 1,000–1,400ml (about 4–6 cups) daily for a 20kg dog. Dogs eating dry kibble need more drinking water than dogs on wet or fresh food diets. Always keep clean, fresh water available.

Water Content makes up 86.87% of your dog's total daily nutritional requirements by weight.
Dry, sticky gums, loss of skin elasticity (when you gently pinch the skin on the back of the neck, it stays tented rather than snapping back), sunken eyes, lethargy, concentrated dark yellow urine, panting excessively, and reduced appetite. Dehydration can become dangerous quickly, especially in hot weather or during illness.
Healthy dogs self-regulate water intake remarkably well. However, dogs can drink excessively (polydipsia) due to underlying conditions like diabetes, kidney disease, or Cushing's disease. Acute water toxicity (hyponatremia) is rare but can occur during extended water play or from drinking excessive amounts rapidly — this is a veterinary emergency.
| Life Stage | Size | Min | Max | Unit | Notes |
|---|---|---|---|---|---|
| Adult | medium 10-25kg | 800 | 1400 | ml/day | Total daily water from all sources (drinking water plus food moisture). Dogs on kibble need more drinking water. |
| Senior | medium 10-25kg | 800 | 1400 | ml/day | Senior dogs should maintain adequate hydration. Monitor water intake — significant increases may indicate kidney disease or diabetes. |
