Sizes vary widely: lengths reported from about 27.5 to 67 inches, heights roughly 25 to 32.3 inches, and widths about 20 to 38 inches — covering compact crates up to much larger kennels.
Common materials include medium-density fiberboard (MDF), metal (frames or pipes), and wood (frames and boards).
Many indoor crates have four universal wheels (two lockable) for easy movement, adjustable foot pads for stability on uneven floors, and some are sized/finished to double as end tables or coffee tables for placement in living spaces.
Wooden outdoor kennels highlight weather-resistant features such as multi-layer roofs (for example asphalt, reinforced panels, and wooden shingles), precision-sealed wall joints to prevent leaks, and an elevated base or foundation to keep moisture out.
Most indoor and outdoor options require adult assembly and state that tools are provided; one outdoor kennel specifically notes pre-drilled panels and snap connectors for quick assembly in under 30 minutes.
Some indoor crates include a soft, washable mat or cushion as part of the package. Furniture-style and tabletop crates typically offer roomy interiors that accommodate separate bedding.
Several indoor crates highlight chew-resistant metal tubing or sturdy metal pipes, and some outdoor wooden kennels mention treated, chew-resistant walls. Because construction and materials vary, review individual product listings for detailed anti-chew claims and durability information.
