automatic dog waterers

Dog water dispensers are handy for owners who want to make sure their dog has an ongoing supply of clean, fresh water to drink from, without needing to constantly worry about changing water.

What Are Automatic Dog Waterers?

Automatic dog waterers are dog water bowls that provide your pup with ongoing, regular access to clean drinking water. Automatic dog waterers are especially useful for owners who don’t want to constantly be refilling their dog’s water bowls.

While many automatic dog waterers also qualify as dog water fountains, this isn’t true for all of them (several of our best picks below don’t use a flowing fountain system).

What Are the Benefits of Water Dispensers?

Automatic dog waterers are an added bonus for any dog owner. However, they’re especially handy for certain types of owners and dogs.

  • Great For Owners Who Aren’t Home All Day. Owners who are at home with their dogs can change out their dog’s water bowl whenever the occasion arrises. However, owners who are away and are at work all day don’t have this option, so they may choose to use an automatic dog waterer instead, to ensure their pet has a constant supply of fresh water. Don’t forget automatic dog feeders too! Workaholic owners can use automatic food dispensers to feed their pups if they regularly can’t make it home for dinner time. Treat-throwing dog cameras can also be handy for keeping an eye on your dog while you’re away.
  • Disabled or Immobilized. Owners who have a hard time getting around may choose to opt for an automatic water dispenser. This will save them several trips to the sink and back, as well as help them avoid the need to crouch or bend over in order to fetch the water bowl.
  • Those Who Are Forgetful. How many times have you gone over to your dog’s water bowl, only to find it empty or with clumps hair and food in it? Sometimes we simply forget to check as often as we should. If you tend to be a forgetful person, an automatic dog waterer could be a solid solution.
  • Dogs Prone to Kidney Disease. If you know that your dog is susceptible to urinary or kidney diseases, an automatic dog waterer can help prevent these illnesses through increase hydration.
  • Picky Drinkers. Some dogs won’t drink from their water bowl unless it’s fresh water. If you’re concerned that your dog isn’t drinking enough and could potentially be dehydrated, a dog fountain is a solid solution.

Wondering if your canine might be hydrated? This video from Dr. Questen can help you determine if your pooch needs to up their water intake!

If you realize your dog is potentially dehydrated, you’ll absolutely want to consider investing in a dog waterer or dog fountain.

  • Wall Mount. Can be mounted on a wall or fence.

Owners love the raised design, sturdiness, and ease of use. It’s basically a toilet tank for your dog – simple, but gets the job done!


You may want to purchase a dual faucet adapter, since this device will take up one of your outdoor faucets. There are a few complaints of leaking, but most are very happy with this device.

Needing an electric outlet to plug into is a con and it would be helpful to identify fountains that need one.

Ben Team

Not sure we’d consider needing electricity to run a “con,” Linda. But, you bring up a good point — we’ll work on getting that information added ASAP.
