Whether shopping online or offline, it’s important to keep a few factors in mind. But it’s not always a straightforward process because there are so many waterers available out there. Here are the key features we think you should keep in mind in that case.

Capacity – Best Automatic Dog Waterer

How much water can the waterer keep? Of course, the more, the merrier. When the container is large, you only need to keep refilling it every so often.

Filter for Best Automatic Dog Waterer

This is quite an important feature especially if you’re not too sure of the sources of your water. Whenever you’re outdoors, the last thing you want to worry about is the quality of the water you left on your pooch’s container!

Water Level Indicator

This is a pretty basic one. We believe that a good waterer is one that provides you with a clear view of the amount of water remaining. This way, you can see if your pooch is drinking enough water per day. And also, you can tell when to refill the container.
