How Much Water Should a Dog Drink a Day?

1 How Much Is Normal

Water needs scale with weight and differ by age: a puppy about 80 ml per kg per day, an adult about 100 ml per kg. Too little invites ‘heat’ and directly burdens the kidneys, raising the odds of stones and urinary disease, so keep intake adequate daily.

2 Signs of Dehydration

Mild thirst is hard to read, but severe shortage shows as dry mucous membranes, thick saliva, sunken eyes, and dullness. Left unchecked it becomes serious dehydration with lost skin elasticity and lethargy that needs clinic fluids.

Long-term low intake also brings hard, dry stools and constipation, dark smelly urine, more picky eating, and worse tear staining.

3 Encouraging Drinking

For a dog that will not drink on its own, offer a few sips before each meal and reward with a treat if it drinks.

Carry water on walks and offer some every so often to replace what is lost.

Add a little food to the water for scent that draws the dog in.

For a stubborn non-drinker, switch to wet food — but it lingers in the mouth and raises tartar risk, so brush regularly to keep the teeth clean.
