Doggy Man Far Infrared Warm Heater Tekion with Fluffy Cover Size: 37cm x 27cm (Regular Size) Can be used reversibly at 40°C and 35°C. Comes with a washable, fluffy cover. I tried using the main unit and cover once, but my dog just sniffed it and walked away. The cover has been washed and the power operation has been confirmed before listing. Thank you for looking.
