Summary
Good Housekeeping's top-rated fountain overall after testing 15 models — the quietest of the bunch, stainless steel bowl goes in the dishwasher, and the 3.2L capacity handles multiple pets for days. Comes with four filters included.
Good Housekeeping's top pick specifically for dogs — holds a massive 6 liters and stands nearly 7 inches tall so larger breeds don't have to strain to drink. BPA-free plastic parts are dishwasher safe for easy weekly cleaning.

- Simple two-piece design makes hand-washing quick and easy
Cons
- No visible water level indicator — must estimate by feel or schedule
- Not suitable for large dogs who need more than 3.2L daily
- No smart features or app connectivity
- Filter replacement needed every 2-4 weeks
- Short 3.8-foot cord may require an extension cord depending on outlet placement

Our take
For most dog and cat owners who don't need smart features, the Rellaty is the sweet spot: genuinely quiet, easy to clean, and built from stainless steel at a price that won't hurt. It's the 'set it and forget it' pick.
If you have a big dog, this is the one. The elevated design and huge capacity solve the two biggest problems dog owners face with fountains, and the simple two-piece construction means cleaning takes minutes.
