How Much Water Does A Dog Need?

Your dog is more like you than you think…at least when it comes to drinking water.

Like you, a significant amount of your dog’s body weight is water—around 60%. Also like you, water plays a vital role in many of the functions and systems inside the body of man’s best friend. That’s why it’s important to keep your pet hydrated just like the rest of the family.

Why Is My Dog Drinking So Much Water?

Because dogs come in so many shapes and sizes and have different levels of activity, their hydration needs will vary too. A pit bull is going to have different water requirements than a Chihuahua. So, when you add a furry friend to the family, it’s important to have a conversation with your veterinarian about water intake. You’ll also want to pay attention to your dog’s behavior and demeanor at home—your pet can tell you a lot even though he can’t talk. 

Do you know how much water your dog should drink each day? Around 0.81.7 oz. per pound per day is a good rule to keep in mind, but make a plan with your vet that takes your dog’s size, weight and activity into consideration. 

Dogs are susceptible to both dehydration and water intoxication. Some dogs can become obsessive about drinking water. If your dog drinks more than 2 oz. per pound of body weight per day, and/or cannot go through the night without urinating on its bed or the carpet, call your Vet to discuss your concerns.

How Much Water Does My Dog Need?

A dog is an important member of the family. He’s the loyal greeter who is excited to see you when you get home from work every day, friend and protector of your children, your morning walking buddy and so much more. It’s no wonder people often call their dogs their “fur children.”

And he doesn’t ask for much in return: food, exercise, the occasional treat, a little—ok, a lot—of affection, and of course, water.

Just like the other members of your family, water is a vital component of your dog’s life. Understanding and meeting your pet’s water needs will go a long way in making your home a happy place for your dog.
