The Best Dog Water Dispenser Reviews

Best Indoor Dog Water Dispenser

1. PetSafe Drinkwell Dog Water Fountain

The PetSafe Drink Well Platinum Dog Water Fountain is my top pick for the best indoor water dispenser.

It is made of durable, BPA-free plastic has a large water capacity which is ideal for a small dog. BPA-free plastic is an important feature to look for regardless of which brands you’re going to buy. In layman’s terms, BPA-free plastic means it is safe for food use and there are no chemicals that can contaminate the drinking water.

With 168 ounces capacity and a built-in water reservoir system, you might just need to fill the water feeder once a week or twice (if you have a single small dog). It is easy to clean the pump of any debris and you just need to clean the stainless steel, plastic, or ceramic bowl to keep it in a good condition.

This drinking fountain also features a replaceable carbon filter that can remove bad tastes and odor from the water. The last but not least, it also has an adjustable water flow control that allows you to customize how much water flow.

Best Outdoor Dog Water Dispenser

2. Easy-Clean Water Bowl

This Easy-Clean water bowl is the best outdoor water dispenser.

It is easy to use, just connect it to the garden hose, turn on the faucet and it’s all set; I just needed 5 minutes to install it.  Although theoretically, you can use it for indoor use (by connecting it to the tub of a washing machine) I wouldn’t recommend it because it’s not designed for indoor use.

This outdoor waterer has a compact valve that will keep the water level in the drinking bowl in check and prevent any overflow. The metal hose and fittings are very well made with great quality. There two different sizes available: 5 feet and 10 feet.

3. PetSafe Drinkwell Big-Dog Pet Fountain

With 288 oz. water capacity or equal with 10 liters or 2.5 gallons, The PetSafe Drink Well Big Dog Water Fountain is an ideal drinking fountain for large dogs

It is dishwasher safe and features a charcoal filter to the water fresh and clean. There is also an anti-bite cover to protect the cord from being chewed.

And you can optionally control the flow of the water through adjustable flow control. The dish is also pretty deep (5-inches deep dog water bowl) so you don’t need to worry your dog will spill and splash the water all over the floor as he drinks from the drinking bowl.

4. PetSafe Ceramic Dog Water Fountain

This stainless-steel water fountain can be a great choice if you have more than one puppy under one roof.

 It has 360-degree design and interchangeable spout rings that can be easily customized to provide 1 to 5 free-falling streams at the same time making it easier for all your fidos to all go drink together without squeezing themselves.

With 70-ounce water capacity, the water should be enough for a day or two if you have two or three small to medium-sized canines. You can also increase or decrease the flow of water with an adjustable flow control lever.

The submersible pump is fairly quiet and the receiving ramp reduces the sound of falling water. There is also included a replaceable water carbon/charcoal filter and a foam filter to keep the water fresh. It is easy to clean, hygienic, and dishwasher safe.

5. PetSafe Drinkwell 2 Gallon and Big Dog Pet Fountains

The PetSafe Drinkwell 2 Gallon Dog Water Fountain is a great option if you have multiple large dogs at home.

With a reservoir of 2-gallon water, this large dog water dispenser is designed to provide your entire pet’s household with enough water. It is made of BPA-free plastic design free from toxic chemicals that could contaminate the water.

When you have multiple pets, doing regular cleaning is even more important to keep dog hair, bits of foods, dust, and other debris from accumulating. The good news, the dog water bowl is designed with no hard to reach crevices and dishwasher safe so you can clean it easily and quickly.

The water dispenser features dual filtration consisting of foam filter to protect the pump from hair and debris, and carbon/charcoal filter to remove bad tastes and odors from your pooch’s water. You can also increase or decrease the water flow or turn it off altogether to make it run quietly.

6. Automatic Farm Grade Stainless Stock Waterer by

The Automatic Farm Grade Stainless Stock Waterer by is an ideal outdoor waterer for dogs, cattle, goats, and sheep.

It’s made of 304 top quality stainless steel. The surface won’t break or rust under normal use and care. However, you should be careful not to drop chlorine in the water since it is acid and can break down the rust protection.

It holds a half-gallon of water which should be enough for your furry friend. This automatic dog water dispenser will keep refilling once it is connected to a water hose, so your buddy will have a continuous supply of clean water all the time.

It can be connected to any garden hose but the water hose adapter is not included in the package, you need to buy it separately.

7. MUDUOBAN Stainless Steel Automatic Waterer

The Stainless Steel Automatic Waterer Bowl by is made of durable, high quality 304 stainless steel (which means no rust and no deformation).

The waterer uses a float valve to detect low water level concentration and automatically replenish the water as your pooch drinks.

It can be connected to a garden hose through a 1/2″ size connector so you don’t need to constantly check the water level of the stainless steel bowl to make sure there is enough water to drink.

The connector is not included and getting it from local hardware stores can be quiet a hassle, therefore, I would strongly recommend ordering both the hose and metal connector along with it at Amazon.

8. RPI H2O Animal Hydration Automatic Waterer

If you prefer dog waterer that can be mounted to the wall, you would love this H20 Animal Hydration Automatic Waterer.

Not only to the wall you can also install it to the fence, or anywhere at the height that is most comfortable for your fido to drink.

It can be connected to a garden hose, and as long as the hose is still connected (and turned on) then the float valve will keep providing a continuous stream of clean, fresh water for pets to drink. With a large capacity of 1 gallon, you won’t ever need to worry that your buddy is not drinking enough water. Moreover, it’s easy to clean, there’s a large drain at the bottom that you can plug easily when you want to clean it.

Some people might have a concern with the material it is constructed from. The polypropylene material is made of might not as heavy-duty as the other materials such as ceramic or stainless steel but it’s still strong enough. I have used this waterer for 1 year without any sign of fading or breaking down.

9. H20 Animal Hydration Flow Automatic Waterer

The H20 Animal Hydration Flow Automatic Waterer is another great automatic water dispenser made by the H20 company.

It’s used for outdoor use and can be attached to any garden hose to provide a constant supply of clean, fresh water for your pooch to drink. With a mechanical float valve that fills up the stainless steel bowl as fast as when it’s being drained.

It’s made of heavy-duty stainless steel with a high-density polypropylene cover. The downside, you definitely have to keep it out of the sun to keep some algae from forming. Another thing that I don’t like is the hose connection is plastic, making it easy to leak and break.

I read it in the customers’ review, there was this one guy that managed to “leak-proofing” his dog waterer and shared the tips there. Considering almost all outdoor dog waterers have an issue with a leaking hose connection, you may want to read his helpful tips here.

Who Should Buy a Dog Water Dispenser?

Your dogs need to drink a lot of water to stay hydrated and healthy; otherwise, a variety of health problems can arise. Regardless of the types, pet water dispenser is proven to be effective in making sure your pup gets a continuous stream of water. And unlike water left in his bowl that can become stale after several hours, water pouring from a water dispenser is always fresh. This means they are more likely to drink throughout the day.

Thanks to the water dispenser’s foam or carbon filter, the water provided are clean and uncontaminated as this filter cleans the water of dirt, debris, and bacteria. The carbon filter also removes bad odors from the water, which makes the water taste even better for your canine.

4 Types of Water Dispensers

Dog water dispensers are varied on the market depending on the purposes. Here are the most common four.

Gravity Dog Water Dispenser

Gravity waterer is the simplest and easiest type of dispensers available on the market. It doesn’t require electricity and works on a very simple principle. 

The basic set up is to connect a water reservoir to your pet’s water bowl upside down. Then, harnessing the power of gravity, the water will start to flow into the bowl until it fills up. The drinking water will stop flowing once it reaches the opening of the reservoir and continues to trickle again after your fido takes a drink from the water bowl and lower the water level.

Dog Water Fountain

A dog fountain is great for indoor use. This product uses a submersible pump that is powered by electricity to keep the water level constant. This free-falling stream is attractive for many dogs since it’s rooted in their genes to drink from running streams of water over still water. It doesn’t matter whether your fido drinks from the water streams or from the drinking bowl, the quality of the water stays the same and good for drinking.

Automatic Dog Water Dispenser

The automatic dog water dispenser is quite popular for outdoor use. It is easy to operate, you just need to connect it to a garden hose or any other water source to provide an adequate amount of clean and fresh water when your dog is playing outside. This pet water dispenser uses a float valve system to regulate the amount of water circulated and keeps the water from getting spilled over.

Portable Water Dispenser

A portable dispenser uses the same principle with the gravity waterer to make it work. But instead of using a large reservoir, it utilizes a water bottle fixed to your dog’s water bowl for a source of water. The included bowls can be detachable or foldable, which makes it quite handy when not in use.

Due to their small sizes, you can easily carry this bottle dispenser with you when you’re on a road trip and your dogs need to drink. You can also fix it on the inside or outside of your dog’s crate and attach a faucet to the bottle. Your dog can then lick the nozzle attached to the faucet to flow out the water.

What To Look For When Buying a Dog Water Dispenser?

Here are a few tips to keep in mind before buying a water dispenser for your dog.


Before you look at anything else, you need to make sure you get the right type of water dispenser. Some water dispensers are designed exclusively for indoors or outdoors uses while others are designed for both areas, such as a pet water fountains.

If you travel a lot with your pooch or participate in outdoor dog sports events often, you may want to opt for an easy-to-carry portable water dispenser.

Size and Capacity

Different sizes of dogs require different amounts of water to drink. This means you need to choose a water dispenser that has a large enough reservoir and adjustable flow control to fulfill your dog’s hydration needs. For example, if you have big dogs like German shepherds, you may want to go with a dispenser that comes with 70 oz capacity.

Together with large water capacity, you also want to consider the drinking bowl’s size and the depth of the container. Make sure the drinking bowl’s size matches the size of your dog’s food bowl.

Also, consider your dog’s muzzle size. If he had a long muzzle and liked to dunk his entire muzzle into the water bowl to drink, it would be best to get a more bottomless dog bowl.


Manufacturers use these three materials to make pet water dispensers: ceramic, stainless steel, and plastic. Plastic is the cheapest among the three, but I would suggest avoiding plastic dispensers as they are the easiest to damage and tear, which makes them have the shortest lifespan among the three options.

Although ceramic and stainless steel cost a bit more, both are a better option, as they are more durable and resilient over a longer period of time than plastic. Stainless steel provides a better advantage for your dog’s health since the material doesn’t contain any harsh chemicals to ensure the water won’t be contaminated.

Filtration System

A good filtration system is a must if you want to make your pooch drinks the best water. Most manufacturers build either foam or charcoal filter into their products. Both work well to keep the water clean and free of contaminants and other harmful particles, so you don’t need to worry about which one that your chosen dispenser use.

Remember, though that you need to replace the water filter from time to time (generally every three months or so), so there is a recurring cost that you’ll have to bear. Therefore, you want to make sure to check if the replacement filters of your chosen product are readily available or not. As for the cost, most replacement filters are quite cheap, it will cost you no more than a few dollars.


As all water dispensers need to be cleaned regularly from stuck dog hairs, clinging bits of dog foods, and other dirt, you want to check whether the water dispenser is easy to clean or not. Some pet dispensers are dishwasher safe, while others need to be washed in the sink. Cleaning is also a breeze if the dispenser can be assembled and disassembled in just a few steps.
