Water is one of the essential things required for survival by all living creature. No human, animal or plant can go long without the intake of water. Similar to every living being, dogs require a certain amount of water everyday so that they can go about their activities while staying healthy and hydrated.

If you go out quite often and are unable to take your dog along, you would know how important it is to leave your dog with enough water for it to stay hydrated. Or maybe you are just playing around in your backyard with your kids and family and want to save yourself from the hassle of filling out the dog waterer every now and then.

What Is an Outdoor Automatic Dog Waterer?

A normal dog requires at least 0.75 to 1 ounce of water per pound of weight every day. Although the dog might get some hydration from its food, an adult dog would still require somewhere around 20 to 100 ounces of water every day, while a puppy would require at least 8 to 20 ounces of water each day.

For dogs that mostly remain indoors, a standard bowl of water does the job perfectly, but when it comes to a dog that stays outdoors such as in the lawn or backyard, an automatic dog waterer becomes more of a necessity to provide clean and fresh water to your dog.

An outdoor automatic dog waterer can be anything from a container or bowl to a running fountain that can be placed in any outdoor area, particularly in the backyard. It can be connected to a water supply so that it can be filled again and again. There are automatic fillers that keep filling the bowl as your dog drinks water, which keeps the water fresh and clean.

Dog water fountains come in different types. Some fountains come with a pressure pad that your dog can put its feet on so that they will start sprinkling water. Others keep on running automatically so that your dog can easily get fresh water at any time.

The Benefits of an Automatic Dog Waterer

There are several benefits that come with an automatic dog waterer outdoor and dog water fountain outdoor. Firstly, they are extremely important for freshening up and hydrating your dog, especially in the hot summers. They also provide a good environment and a lot of convenience for dogs living outdoors.

Unlike a traditional dog waterer or a bowl, these auto dog water dispensers or auto dog water fountains come with a built-in filtration system that keeps the water fresh and clean from bugs, feathers or any other kind of mess.

Many studies show that animals generally prefer running over stagnant water due to their natural ancestral instincts. Furthermore, moving or running water has a better oxygen content, which keeps the taste better and fresher and helps the water stay cool.

What to Consider Before Buying?

The market today is flooded with different types and variations of automatic dog waterers outdoor and automatic dog fountains, which makes it hard and confusing for most people to choose one option. These variations also come with different price tags, ranging from just $10 to more than $100.

You can decide the budget beforehand, but if budget is not an issue, you can consider the following factors first before you choose a particular model:


The material of the waterer is very crucial in determining its life, reliability and durability. Stainless steel is considered to be the best material because it is the most durable and easiest to clean.

You can also opt for plastic bowls, but you will need to ensure that they are BPA-free as well as UV-resistant because they will be placed in the sunny outdoors.

If you are going for fountains, they should be made with materials that are outdoor-safe and -friendly. The pumps, adapters, cords and all the other parts should be suitable for the outdoors to avoid any unfortunate accidents.


The size and capacity of an automatic dog waterer outdoor is another decisive factor in the buying process. The size of the bowl should be big enough for your dog to easily drink water from. Any bowl which has a capacity of less than 24 ounces is too small for a dog.

Even for fountains, the basin should be big enough to avoid spilling when the dog is drinking water so that it can easily drink.

Auto-Filling Ability

An auto-fill feature is incredibly convenient to have. Although it might significantly increase the price of the product, it will save you from the trouble of manually refilling the waterer.

Even fountains come with an auto-fill system where they are connected to a water source and keep getting refilled whenever required.

An auto-fill system is extremely important, especially if you are leaving your pet unattended for long periods and there is a chance of the water running out.


Filters are another important part of the whole automatic dog waterer outdoor system. They make sure the bowls stay clean from all the outdoor debris, chemicals and any other mess. Automatic filters keep working and cleaning the water by themselves, washing out all the dirt or any other mess that might land on the water’s surface.

Why Is Fresh Water Important for Your Dog?

It is true that a balanced diet is very necessary for your dog, but what is equally important is your dog’s water intake. Since water is an important component of a healthy body, your dog will not be able to function properly without it. To save your dog from dehydration, timely provision of water is very important.

Water is beneficial because it helps move the nutrients around the dog’s body and through the cells. It also helps make the digestion process easier and more effective. Moreover, water contributes to maintaining the body temperature and keeping the body cool, especially during the summer days.

Water also makes movements easier for your dog by lubricating the joints. It also aids in the removal of harmful substances from your dog’s body through urination.

Thus, water plays a vital role in keeping your dog healthy and active throughout its lifetime. Without an adequate supply of water, your dog might end up getting ill or dehydrated.
