K&H Heated Thermal Bowl Blue 1.5 Gallon 25Watt

 
The K&H Thermal-Bowl™ heated dog water bowl is thermostatically controlled to prevent your outdoor dog’s drinking water from freezing. No matter how cold the temperature, the heater inside the Thermal-Bowl keeps water unfrozen and drinkable.
For added protection, all Thermal-Bowl™ electronics are safely sealed inside to prevent water damage and facilitate outdoor use. The 5.5 foot power cord is steel wrapped to prevent abrasion and resist chewing.

This heated dog bowl uses only 25 watts and is energy efficient. It's MET listed and can be used indoors or outdoors.
