K&H Granite Thermal Pet Bowl, 1.5 Gallon is designed to keep your outdoor dog's drinking water from zing during cold winter months, ensuring your pet has access to fresh, drinkable water. This innovative bowl is thermostatically controlled, with internal thermostats that automatically turn on and off as needed to maintain the water temperature above zing. For added safety, all electronics are securely sealed inside to prevent water damage. The bowl features a durable 5.5-foot steel-wrapped power cord that resists abrasion and chewing, making it for pets who like to nibble. It can also be used indoors simply by leaving the unit unplugged. Energy efficient, this bowl uses only 12-25 watts of power. Measuring 10 inches in diameter and 4.5 inches in height, it holds up to 1.5 gallons of water, providing ample hydration for your pet throughout the day.
