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 Trailblazer’s layout
First confirm which Trailblazer you own. The recent small crossover and the older, larger SUV with the similar name should not inherit one another’s kennel fit advice. For the modern crossover, begin with the rear seats upright if passengers ride behind you and treat the area behind them as the everyday kennel envelope.
The hatch opening and the narrowing space near the rear glass deserve as much attention as floor length. A kennel may sit neatly on the cargo mat but meet the hatch at its top corners. If you fold a rear seat, check the change in floor height and how the kennel will be supported and secured rather than assuming the resulting space is a continuous flat platform.
Pack a realistic weekend load around a cardboard mock-up before buying. You should still be able to attach the leash, open the kennel and reach water without removing unsecured bags onto the roadside. If the dog needs more interior space than the vehicle can accommodate, a suitable vehicle restraint or a different seating plan is the next question. The model’s SUV label is not evidence that a large kennel will work.
The checks that matter here
- Modern crossover versus older TrailBlazer generation
- Rear-glass slope and upper kennel corners
- Folded-seat floor transition and loading access
Kennels we would compare for the Chevrolet Trailblazer
We would first investigate the smallest RuffLand configuration that is genuinely appropriate for the dog, not the smallest one that happens to fit the vehicle. Compare a suitable Gunner G1 only after confirming the available exterior envelope. In this compact layout, a second kennel door earns its place only when you retain an unobstructed route to it through the passenger area.
RuffLand single-door kennel
Start with the dog-appropriate interior, then test whether that configuration leaves a usable rear-loading route in the compact Trailblazer.
When we would pass: Reject a result taken from the older large TrailBlazer SUV when your vehicle is the recent small crossover.

Gunner G1
Compare only after measuring the Trailblazer cargo envelope with the required rear seats occupied; a size label cannot establish clearance beneath the closed hatch.
When we would pass: If folding a rear seat introduces an unsupported transition beneath the shell, solve the installation before buying.

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.
