Breeders, pet owners, and veterinarians have been using K&H Pet Products Original Lectro‐Kennel Outdoor Heated Pads to warm pets for more than 50 years. Use this unique heated dog pad to keep your special pet warm in even the coldest temperatures, whether outdoors or indoors. Its internal thermostats automatically heat to a dog's natural body temperature and will turn on and off as needed to keep them warm and safe. We build this durable heated pad with tough ABS plastic and a 5.5 foot steel-wrapped cord. For added protection, drill holes through the outer lip of the Lectro-Kennel and screw it down to the floor or onto the wall. Whether outdoors or indoors, use the K&H Lectro-Kennel anywhere a flat, stable surface is available. Its water-resistant build is perfect for dog houses, porches, garage floors, barns, or even the living room. The K&H Lectro-Kennel Outdoor Heated Pad has been tested & certified by MET Labs and exceeds USA/CA electrical safety standards; K&H doesn't just use safety listed parts, we safety certify the entire product. For indoor/outdoor use with 110/120 volt electrical current only.
