PetSafe Oasys 2 Gallon Pet Fountain — Large-Capacity Plastic Fountain for Dogs

The PetSafe Oasys 2 is a large-capacity plastic fountain designed for big dogs and multi-pet households. It holds 2 gallons (256 oz), offering extended refill intervals for active households. Features include an adjustable flow control to customize water speed or disable the stream for quiet operation, a built-in pump and filter, and a practical open bowl design that ensures pets can drink even during power outages.

The fountain is constructed from durable plastic and is top-rack dishwasher-safe (pump excluded), with a simple design that avoids hard-to-reach crevices. It includes one-stage filtration that captures debris and helps freshen water. The adjustable pump supports varying flow preferences, from active streams to still-water bowls.

Best suited for large dogs and multi-pet families seeking a high-capacity, maintenance-friendly option. The open-bowl backup ensures hydration continuity if the power fails—a practical safety feature. Main trade-offs: plastic construction can harbor biofilm over time, and replacement filters incur recurring costs. Pump longevity and noise quietness are commonly cited variability points across user reviews.
