Summary
WIRED's pick for best cordless stainless steel fountain — fully stainless construction resists bacteria better than plastic, and the rechargeable battery lasts up to 60 days. A visible water level window and three flow modes round out a well-thought-out design.
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.

Our take
For pet owners who've dealt with chin acne or slimy plastic bowls, going all-stainless is a game changer. The 60-day battery life means you can put this anywhere in the house without worrying about cords.
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.
