Lectro kennel has been warming pets for over 30 years. It is ideal for use in a doghouse, kennel, porch or anywhere extra warmth is desired. Dual thermostats maintain a surface temperature of 12-15 degrees above ambient air temperature, then warms to a comfortable 102 degrees when in use by your pet. The unit is constructed of rugged ABS plastic and steel wrapped cord. It can lie flat on the floor or be attached to the wall of the dog's house so the dog can lie against it. Be sure not to cover the entire doghouse floor with the lectro-kennel, as you dog should have a choice to be on or off the heated pad. If mounting on a wall, take precaution not to drill through or puncture the pad in any way, as the pad is an electrical device. When using as a whelping pad or for geriatric pets, use the lectro-temp control to lower the pad to the desired tempature. We also offer a cover in each of the three lectro-kennel sizes. Lectro-covers are designed to attach to the lectro-kennel pad for added comfort for your pet. They are made of faux lambskin and are machine washable.
