You just can’t fit a square peg in a round hole! That’s why we invented the Igloo Style Heated Pads to fit into any Igloo style house. Round, or Dome shaped doghouses have been a best seller for years and the Igloo Style Heated Pad is the answer to provide warmth for the animals using these homes. It’s half round shape fits easily through the door of the home and allows for the pet to stay on or off the heated surface. Constructed the same as Lectro-Kennel, the Igloo Style Heated Pad will provide reliable, affordable comfort. UL and CUL listed.
