Research-based shortlist, not a verified-fit list. Confirm your model year, body style, trim and seat layout before buying.
This guide builds on our general guide to choosing the best kennel for your vehicle. Start there for the overall approach, or change vehicles with the selector below.
Start with your Chevrolet Colorado’s layout
For a Colorado, begin inside the passenger cabin. A midsize pickup’s useful kennel space is controlled by its cab, rear doorway and front-seat positions, not by the cargo bed’s length. Identify the model year and cab configuration before comparing photographs: older and newer Colorado generations do not offer the same cabin choices or interior geometry.
Set the driver and front passenger seats for the people who actually travel in them, then measure the rear opening and intended installation area. Check floor contours and seat hardware without assuming that a folded cushion creates an approved mounting surface. If a child or adult needs the adjacent rear seat, keep their seat belt, foot space and exit route fully usable.
The bed is a separate transport problem, not an automatic fallback when a kennel fails the cabin check. Exposure, temperature, exhaust and securing arrangements need their own properly planned solution. For ordinary family travel, a documented cabin restraint or carrier appropriate to the dog may be a better route than forcing a rigid kennel into an unsuitable space. Test the entire loading motion before ordering.
The checks that matter here
- Exact model year and cab configuration
- Rear doorway with front seats in driving position
- Seat hardware and an instructed securing method
Kennels we would compare for the Chevrolet Colorado
A compact, dog-appropriate RuffLand configuration is a candidate to investigate only if its exterior shell can pass through the rear doorway and be secured as instructed. Compare a Gunner G1 separately; the dog’s required size may rule it out before installation becomes possible. We would not move to a smaller interior size merely because the pickup cabin is tight.
RuffLand single-door kennel
Investigate only if the dog-appropriate kennel passes through the Colorado rear door and can be installed in the enclosed cab as instructed.
When we would pass: Do not retain this candidate if a rear passenger loses a usable belt, foot space or exit beside it.

Gunner G1
A separate cab-fit candidate for the Colorado: check the doorway, seat arrangement and complete shell before assuming a required size can be accommodated.
When we would pass: A newer Crew Cab photo cannot substitute for the rear doorway of a different Colorado cab or generation.

These are candidates to investigate, not confirmed fits. Match the exact size and installation instructions to your dog and vehicle before ordering.
Before you order
Use the main guide’s dog-sizing and loading-route checklist to test your chosen layout. Review how to check crash-test evidence for the exact product and installation; a successful physical fit does not establish crash protection.
Bring your dog’s measurements, your model year and trim, and photos of the intended installation area to the kennel seller. Ask for the exterior envelope and usable interior measurements of the exact size and door configuration. Confirm the return terms before a trial fit.
