Insulated dog houses are designed for either indoor or outdoor use, though some can be used in either situation.

Indoor insulated dog houses are closer to dog beds than dog crates. Their insulation is made of essentially nothing but soft, naturally warm materials like fleece. These are rarely safe for use outside as they won’t last long. Some can be collapsed for use as a safe traveling space.

Outdoor insulated dog houses are designed to keep your dog both warmer in the cold and cooler in the summer. How they’re insulated varies. For example, some use multi-layered walls and floors, while others may use heavy-duty foam construction. You can often use an outdoor house indoors, though these may be too large to fit inside comfortably.

Size

Insulated dog houses come in as many sizes as there are breeds of dogs. OK, maybe not that many sizes, but you have a guarantee of finding a perfectly sized house if you look long enough.
