If you have a big dog or multiple pets in your family, the 2 Gallon Pet Fountain is the perfect size! Pets love running water and are drawn to it. Pet fountains entice pets to drink more water which keeps them healthy and hydrated. With this fountain, pets can drink from the free-falling stream or the bowl (which is awesome) because your pet needs 1 ounce of water per 1 pound they weigh every day. This fountain has adjustable flow control which lets you customize the free-falling water stream, so no matter your pets personality, theyll feel comfortable drinking from their new fountain. Weve designed the fountain to be tip and spill resistant, so you wont have to worry about cleaning up puddles. Also, the open bowl means that even if the power goes out, your pet will still have access to water. To keep water fresh, we use dual- filtration technology to remove pet hair, debris, bad tastes and odors. A carbon filter, foam filter and fountain pump work together to keep water filtered and clean, and the constant circulation helps to prevent bacteria growth. This plastic pet fountain is top-rack dishwasher safe, and weve designed it with no hard-to-reach places to make cleaning simple all youll need to do is handwash the pump separately. Your pet deserves the best. Trust PetSafe to keep your pet healthy, safe and happy.
