Overview
Grey fir wood and a waterproof finish define this Rockever outdoor dog house, which measures 40 inches wide, 26 inches deep and 26 inches high with a window and a door flap.
The listed dimensions put it in the medium dog breed size range, and the classic peaked-roof style is aimed at outdoor use, though the listing also mentions indoor suitability without detailing what changes between the two settings.
- 40-inch W x 26-inch D x 26-inch H grey fir wood house
- Waterproof build for outdoor use
- Window plus door flap entrance
- Ships with instructions and screws for assembly
Who it's for
Best suited to medium-sized dogs kept outdoors, where the waterproof fir wood construction and window earn their keep. Large or giant breeds will find the 26 by 26 by 40 inch footprint too small.
Strengths and trade-offs
Drawn from this product's published specifications.

Performance notes
