Quick answer
A water fountain for dogs stimulates water intake by offering running, filtered water. Dogs that normally drink little drink on average 30–40% more from a fountain than from a static bowl. Capacity: at least 2L for small dogs, 3L+ for medium and large dogs.
Dogs need significantly more water than cats — a 10 kg dog needs 500–700 ml daily, a 30 kg dog needs three times that. The problem: many dogs don't drink enough from a static bowl. Running water is associated in the animal brain with "clean" and "safe" — an innate reflex that both dogs and cats have. A water fountain for dogs plays directly into that.

|---|---|---|---|
| Under 5 kg | Chihuahua, Yorkshire terrier | 125–250 ml/day | 1.5 L |
| 5–10 kg | Beagle, Cocker spaniel | 250–500 ml/day | 2 L |
| 10–20 kg | Border collie, Bulldog | 500–1000 ml/day | 2.5–3 L |
| 20–35 kg | Labrador, Golden retriever | 1000–1700 ml/day | 3.5 L+ |
| 35 kg+ | Bernese mountain dog, Great Dane | 1700–2500 ml/day | 4 L+ or multiple bowls |
