What Is FounTaiL? FounTaiL is a wireless dog water fountain designed to replace or supplement a conven-tional water bowl. According to the brand, its flowing-water design is intended for dogs that show a preference for moving water. The fountain is made from 304 food-grade stainless steel and has a stated capacity of 4 liters, or approximately 135 ounces. Unlike a conventional plugged-in fountain, FounTaiL uses a rechargeable battery. The company claims that the battery can provide up to 30 days of operation on a single charge, although actual battery life can vary depending on usage and operating settings.
