Which size does my dog need?

The 4L fountain is designed for small dogs. This size will be more than enough for daily use. 

The 7L fountain is better suited for medium or large dogs, or households with multiple pets. It holds more water, so you won’t have to refill it as often, especially if your dog drinks more throughout the day.

Is it easy to setup?

Yes! Setting it up takes less than 2 minutes. Here’s how:

Step 1: Insert the filter into the designated slot.
Step 2: Fill the stainless steel bowl with fresh, clean water.
Step 3: Turn it on—and that’s it! Your dog now has constant access to clean, filtered water.

The bowl on the floor

Your Dog’s Water Bowl Is Dirtier Than You Think

Your dog’s water bowl may look clean. But it doesn’t stay that way for long. 

Dog bowls quickly develop biofilm — a slimy layer of bacteria caused by saliva, food particles, and stagnant water. Even if you wash the bowl daily, bacteria build up within hours. 


Dogs then end up drinking contaminated water, which affect their digestion, oral health, and overall well-being over time.

Better Hydration for a  Healthier, Happier Dog

Fresh, flowing water encourages your dog to drink more, improving their health and well-being.

Dogs that stay hydrated live longer, healthier lives.

Yet today, most dogs are only offered a stagnant bowl they avoid. Which is why nearly 80% of dogs are now chronically dehydrated.

✓ Flowing water naturally encourages your dog to drink more
✓ Fresh water that keeps them coming back all day long
✓ Proper hydration helps prevent kidney failure and UTIs

"We couldn't believe the difference! Our dogs drink so much more water since we got this fountain. ❤️ It's amazing seeing them choose it over their old bowl every single time. Happy, hydrated pups and one less thing for us to worry about!

Michael Anderson

I’ve bought about 5 different water dispensers for my dog over the last 3 years and they are either cheap, unsafe plastic or collect mould within a few months. So far the Barlow water fountain is exactly as advertised, it constantly looks crystal clear and my dog enjoys drinking out of it!

Serena Brice

Absolutely love this water bowl fountain! 💧 It keeps the water fresh and clean all day, and the gentle flow encourages my dog to drink more. It’s super quiet, easy to clean, and looks sleek in the house. Plus, my dog loves napping next to it — a total win! 🐶✨

"Two dogs, one fountain, no arguments. I refill it on Sundays instead of twice a day. The dishwasher thing is the part I'd actually pay extra for."

Lauren M, Dog Mom

My dog has always been one of those “drink when he feels like it” types, so I was never fully confident he was getting enough water. Since switching to this fountain, I’ve noticed a big change. He goes over to it multiple times a day now without me having to think about it, which is such a relief.

"Five-year-old collie, set in her ways, ignored it for nine days. I nearly sent it back. Day ten she started using it and hasn't gone back to the bowl since."

Both my pups love their new water fountain. Fresh water, ease of use and cleaning is great.

  • Dr. Amelia Brooks

    “As an emergency vet, I’ve seen firsthand how challenging it can be for pet owners to keep their dogs and cats properly hydrated at home. In my experience, the Barlow Water Fountain is one of the few products that can genuinely encourage pets to drink more consistently.”

    Dr. Amelia Brooks,VMD
  • Dr. Natalie Pierce

    “As a veterinarian, I’m always looking for pet products that are simple, effective, and easy for owners to incorporate into everyday life. The Barlow Water Fountain checks those boxes. It was quick to set up, ran quietly, and the dogs I introduced to it showed interest almost right away. I also really like the generous water capacity and stainless steel bowl. Overall, it’s a practical choice for pet owners looking to support better daily hydration.”

  • Dr. Ethan Caldwell

    “In clinic, I have had a few clients switch to this bundle, and the feedback has been encouraging. Dogs adapted quickly to the fountain. From a veterinary perspective, consistency is where most of the benefit comes from.”

More than one animal

One Fountain. Every Pet In The House.


More pets means more bowls, more refills, and more "who drank it all?" moments. One gets there first, another waits its turn, and somebody is always topping something up.

The 7L Barlow holds enough fresh, flowing water for the whole crew, so you refill far less often and come home to water that's still there. One station, one spot to clean, and no more lineup at an empty bowl.

The wide, low basin works for every size. Big dogs drink comfortably without craning their necks, and smaller pets can reach right in.

Sharing the house with more than one pet? Go 7L.

FAQ's

Frequently Asked Questions 

How do I clean it?

Simply unplug the pump, empty the water, and wash the fountain with warm soapy water once a week. No hard to reach corners and since it's stainless steel, it's extremely easy.

It takes less than 5 minutes to clean by hand or you can simply toss it into the dishwasher.

What if my dog doesn’t like it?

Don’t worry! Dogs are naturally curious and love flowing water, so chances are they’ll start drinking from it right away. Even if they are picky.
And if not, you’re covered with our 30-day money-back guarantee. Just contact us and we'll make it right.

How does the filters work?

The Barlow Water Fountain uses a Multi- layer mineral filtration system to keep your dog’s water clean and fresh.

The filter layers work together to:

  • Catch fur and debris so they don’t stay in the water
  • Remove odors and impurities for better tasting water
  • Reduce heavy metals and contaminants
  • Increase oxygen in the water to keep it fresher

This filtration process helps remove up to 99.9% of impurities, giving your dog clean, healthy water every time they drink.

Is it noisy?

Under 25 dB, and the pump only runs when your dog is near it. Most owners say they forget it's on.

Is it easy to setup?

Step 1: Insert the filter into the designated slot. 

Step 2: Fill the stainless steel bowl with fresh, clean water. 

Step 3: Turn it on and that’s it! your dog now has constant access to clean, filtered water! 

Total Setup Time: Under 2 minutes.

How long does delivery take?

We offer tracked shipping on all orders.

All orders are processed by our super careful fulfillment team within 24 business hours.

We are currently experiencing high volume of orders so delivery times, depending on your location, range from 7-14 business days.

We've made returning products super easy. Simply contact us and we'll handle everything.

Can my dog tip it over and make a mess?

No, the Barlow Fountain is built with a sturdy, non-slip base and solid stainless steel body. It stays in place even for big, playful dogs.

What if my dog has never used a fountain?

Leave the old bowl next to it for the first few days. Most dogs investigate within the first hour and switch over on their own. Don't move the bowl away until they're drinking from the fountain regularly.

Which size should I get?

4L for one dog up to 25lb. 7L for dogs over 25lb, or for two or more animals. If you're between the two, take the 7L — nobody has ever complained about refilling less often.

How often do filters need changing?

Every 3–4 weeks with one dog, more often with several or with a heavy shedder. You'll see when — the flow slows and the water stops looking clear.

How long does the battery last?

On a full charge, the battery can last up to 30 days, depending on the selected mode and how often your pet uses the fountain.
 

For extra convenience, the fountain can also be used while plugged in at all times, so you never have to worry about running out of power.
 

This gives you the flexibility to use it wirelessly for a clean, cord-free setup or keep it connected—whatever works best for your home and your pet’s routine.

Can I use it with multiple dogs or cats?

Yes! The Barlow Water Fountain is perfect for homes with multiple dogs or cats. Its large capacity provides plenty of fresh, flowing water so several dogs can drink throughout the day without constant refills.

For households with more than one dog, the larger capacity option helps ensure everyone stays hydrated with clean, filtered water. 💧

How does the refund actually work?

Email us a photo of the tape line any time before thirty day after delivery. We refund the full price to the original card within three working days.

Do you make health claims about hydration?

No. Hydration matters, and your vet will tell you the same. But we can't prove what Barlow does for your specific dog's health, so we don't print numbers about it. What we can show you is whether the water level drops faster. That's what the Drink Test measures.
