How Much Water Does Your Dog Need?

If food is love for your dog, then water is life. Hydration is one of those basic needs that’s easy to overlook because the water bowl sits quietly in the corner, never demanding much attention. But how much water your dog actually needs is a question worth asking—and answering—because dehydration creeps up faster in dogs than most people realize.

The general rule of thumb is that a dog needs about one ounce of water per pound of body weight each day. That means a 10-pound terrier should drink around 10 ounces, while a 70-pound retriever needs closer to 70 ounces. It sounds simple, but real life throws curveballs. A dog who spends the day lounging indoors may drink less, while a dog out on a summer hike or zooming around the yard will need more. Puppies, nursing mothers, and senior dogs all require extra attention to hydration as well.

Signs of dehydration can be subtle but serious: sticky gums, lethargy, loss of skin elasticity, and dark-colored urine. Left unchecked, dehydration can lead to organ failure. On the flip side, don’t worry if your dog occasionally gulps more than usual—sometimes they’re simply cooling down after play or compensating for salty treats. The key is to watch trends. Sudden spikes or drops in water intake can signal underlying issues, from kidney disease to diabetes, and that’s when a vet visit is in order.

Practicality matters, too. Make water available everywhere your dog goes—on walks, in the car, or while camping. A collapsible bowl and a full water bottle are simple tools that prevent big problems. And don’t forget: a water bowl is only as good as it is clean. Wash it regularly to prevent bacteria, slime, and other contaminants from discouraging your dog from drinking.

Among 13 other features, Timberdog designed RuffRest with a hydration pocket that stores up to a 48-ounce bottle, so you'll never forget your dog's watering needs again.

In the end, hydration isn’t complicated, but it does require awareness. Refresh your dog’s bowl daily, keep it clean, bring water when you’re out, and know the signs of thirst before they escalate. It’s a small habit with big payoffs: a healthier, more energetic dog who can keep up with you wherever life leads. Love may be what binds us to our dogs, but water is what sustains them.
