Inside the range
Hard Shell Protection
Unlike fabric models, these use thick plastic to create a rigid barrier. This is the primary choice for dogs that spend significant time outdoors.
Substantial Sizing
The 46-inch length makes these some of the largest models available. They are specifically intended for extra large dogs that need room to turn and settle.
Weather Resistance
The plastic walls are naturally weatherproof, helping to keep the interior dry during rain. This makes them a reliable year-round outdoor solution.
Multi-Environment Use
While built for the outdoors, the clean plastic lines also work for indoor placement. They are easy to wipe down and maintain in any setting.
First-hand
Buyer notes
The weatherproof plastic has held up great through several heavy rainstorms.
This house is huge; my extra large dog finally has enough room to be comfortable.
It works just as well in the garage as it does in the backyard thanks to the durable build.
