How Much Does a Dog Drink?
Q. How much does a dog normally drink every day?
A. The daily water intake for a dog is about three to six ounces of water for every five pounds of body weight — so a 25-pound dog would drink between a pint and almost two pints per day under average conditions. The amount goes up if the weather is hot, the dog is exercising or both. Depending on whether or not a pet eats canned or dry food, up to half of a pet's daily water consumption can come from food.
It’s important to have an idea of what’s normal for your own pet, so you can spot when water intake has changed and talk to your veterinarian about this. Such changes are often a sign of illness, so don’t ignore them.
