10 Best Automatic Dog Waterers 2026 in the United States

The Amazon Basics Automatic Dog Cat Water Dispenser Gravity Feeder and Waterer Set is a practical solution for pet owners with medium-sized dog breeds or multiple pets. With a substantial capacity, this set includes a 12-pound food dispenser and a 2.5-gallon water dispenser, making it ideal for ensuring a consistent supply of food and water. The transparent hoppers allow pet owners to check the levels at a glance, which is quite convenient for busy schedules.

The use of gravity to dispense both food and water means there’s no need for power sources, adding to its ease of use. Constructed from durable polypropylene and rubber, the set is designed to withstand regular use. Anti-skid rubber feet help keep the dispenser in place, preventing spills and messes. The side cut-out handles make it easy to lift and move the dispensers when needed.

Cleaning is fairly straightforward, though it is hand wash only, which could be a minor inconvenience for some users. One notable feature is the extra-wide entry, which makes refilling the dispensers a breeze. While the design ensures functionality and ease of use, it might not be the most stylish addition to your home. However, if practicality and convenience are your priorities, this set delivers on its promises.

The PetSafe Drinkwell Platinum Cat Water Fountain is a versatile and high-capacity waterer suitable for both cats and dogs. With a generous 168 oz (5L) capacity, it is ideal for households with multiple pets or larger animals, ensuring they always have access to fresh, clean water. The replaceable carbon filter effectively removes bad tastes and odors, encouraging pets to drink more, which is great for their health, especially if they are on a dry food diet or have specific health conditions.

You can even customize the water flow to match your pet's preference, making it more enticing for them to drink more often. The plastic construction and grey color make it a durable and neutral addition to your home. However, it might not be the most stylish option available. The added convenience of being top-shelf dishwasher safe means cleaning is relatively hassle-free, an important feature for busy pet owners. The snap-on reservoir lid and rubber feet help keep the unit stable and prevent spills.

At 15.75 inches long, 10.5 inches wide, and 10 inches high, it fits comfortably in most indoor spaces without being too obtrusive. Weighing in at 1.8 kilograms, it is not too heavy to move around if needed. One downside could be the need to replace the filter every 2-4 weeks, which adds a recurring cost, and some users might have concerns about the plastic material's longevity. Nonetheless, PetSafe’s reputation and customer care support provide assurance of quality and assistance when needed. This product is a solid choice for pet owners looking to ensure their pets stay hydrated with minimal fuss.

The RIZZARI Automatic 3L Pet Waterer is designed mainly for cats and small to medium-sized dogs, offering a generous 3-liter capacity that can keep your pet hydrated for a full day or more. Its gravity-fed system refills water slowly, which means less frequent refills—great if you’re busy or away from home for a while. Made from BPA-free, food-grade polypropylene, it is safe and durable, though it does not include a stainless steel bowl, which some pet owners may prefer for hygiene reasons. The transparent body makes it easy to see when water levels are low, so you won’t be caught off-guard, and the split design allows for straightforward cleaning of all parts, helping maintain freshness without hassle. The base has a raised, non-slip design that helps avoid spills or leaks, even if your pet nudges it.

It relies purely on gravity and has no filtration system, so water quality depends on how often you clean and refill it. It's also battery-free, so you don’t need to worry about power or charging. Sized at about 11 by 6 inches and standing just over 10 inches tall, it’s compact enough for most home spaces without taking up much room. If you have a small dog or a cat and want a reliable, simple water feeder without complicated parts or electronics, this product fits well—just be prepared to clean regularly and monitor water cleanliness yourself.
