Dog Travel Crates: How to Choose One That Fits Your Dog and Vehicle
The right travel crate has to fit two things at once: your dog and your vehicle. Check usable interior space, the cargo opening, the crate footprint and the exact restraint setup behind any safety claim before you buy.

Quick Picks
Choose by dog fit first, then check the vehicle opening, cargo footprint and the exact restraint setup behind any safety claim.
Best for a compact CPS-certified setup
GUNNER G1 Small — Ducks Unlimited Orange
Compact rotomolded option with a named CPS-certified crate-and-strap configuration. Best when vehicle space is tight but independent safety evidence still matters.
Best for more interior room with named CPS evidence
Lucky Duck Lucky Kennel Intermediate — Storm Grey
A larger rotomolded option with a named CPS-certified kennel-and-strap-kit configuration. The extra interior room comes with a much larger vehicle footprint.
Best for collapsible storage between trips
Impact Collapsible Dog Crate 30-inch — Black
Aluminum folding design for repeated loading and storage. Choose it for portability and collapsibility, not because it carries the CPS claims of the two rotomolded options.
Start With the Dog and Vehicle Fit
A travel crate can look suitable on a product page and still fail in the vehicle. The interior may not give your dog enough usable room. The outside dimensions may fit the cargo floor but not pass through the hatch. Or the crate may fit physically while leaving no practical way to open the door, load your dog or install the restraint hardware associated with a safety claim.
- Measure the dog first. Compare standing and lying space with the exact crate’s usable interior dimensions, not its outside size.
- Measure the narrowest loading opening. Include handles and other protrusions that can catch on a hatch or door opening.
- Check the resting footprint. Confirm the crate can sit where intended without preventing the hatch from closing.
- Plan the door direction. Make sure the dog can enter and exit after the crate is in its actual vehicle position.
- Plan the restraint setup. If a safety claim depends on a named strap kit, make sure your vehicle can use that configuration.
Do not treat every inch of cargo space as usable crate space. You still need room to maneuver the crate, reach restraint points and operate the door.
Read Safety Claims by Exact Configuration
The Center for Pet Safety separately identifies the GUNNER G1 Small as a 5 Star certified configuration with Strength Rated Anchor Straps and a 30-pound test dog. It separately identifies the Lucky Duck Lucky Kennel Intermediate as a 5 Star certified configuration with the Lucky Ratchet Strap Kit and a 75-pound test dog.
Those statements describe named model-and-restraint combinations. They should not be generalized to every size in a product line, every strap or every installation. The test-dog weight is also not a sizing recommendation for your own dog.
The Impact Collapsible Dog Crate solves a different constraint. Its folding aluminum construction is useful when storage between trips matters, but the manufacturer does not describe this collapsible line as formally crash-tested. Do not transfer the CPS evidence from the GUNNER or Lucky Duck models to it.
Quick Comparison
| Best for | Product | Published fit data | Key constraint |
|---|---|---|---|
| Compact certified setup | GUNNER G1 Small | Inside: 21.75 × 14.5 × 15.5 in. Outside: 24.5 × 18.625 × 19 in; 20.5 in with handles. | Certification depends on the named restraint setup. |
| More interior room | Lucky Duck Lucky Kennel Intermediate | Inside: 30.25 × 20.5 × 22 in. Outside: 32.5 × 22.5 × 24.5 in. | Much larger cargo footprint and 38-lb empty weight. |
| Collapsible storage | Impact Collapsible 30-inch | Outside: 30.5 × 20.5 × 26 in. Interior: confirm before buying. | Folding convenience is not equivalent to CPS certification. |
GUNNER G1 Small — Ducks Unlimited Orange
Best for: a compact rotomolded crate when named independent safety evidence is a priority
The G1 Small has a stated interior of 21.75 × 14.5 × 15.5 inches, with a 16.5-inch widest interior width. Its exterior is 24.5 × 18.625 × 19 inches, or 20.5 inches high when handles are included, and it weighs 27 pounds empty.
Why it works
CPS identifies the G1 Small as 5 Star certified with Strength Rated Anchor Straps and a 30-pound test dog. The relatively compact exterior can also make it easier to fit through a tighter cargo opening than the larger Lucky Duck option.
What to check
Use the 20.5-inch height with handles when checking a tight hatch opening. Confirm your dog fits the usable interior and that your vehicle allows the specified Strength Rated Anchor Straps to be installed as intended.
Skip it if
Your dog needs more interior room or the crate-and-strap configuration cannot be used in your vehicle. A compact exterior is only useful if the interior still works for the dog.
Lucky Duck Lucky Kennel Intermediate — Storm Grey
Best for: more interior space when the larger vehicle footprint and named restraint kit both work for you
The Storm Grey Intermediate measures 30.25 × 20.5 × 22 inches inside and 32.5 × 22.5 × 24.5 inches outside. Its empty weight is 38 pounds.
Why it works
CPS identifies the Lucky Kennel Intermediate as 5 Star certified with the Lucky Ratchet Strap Kit and a 75-pound test dog. It offers substantially more stated interior room than the GUNNER Small while retaining a named independently certified configuration.
What to check
Measure the complete loading path against the 32.5 × 22.5 × 24.5-inch exterior, not just the cargo floor. Confirm the door remains usable and that you can reach the attachment points for the Lucky Ratchet Strap Kit.
Skip it if
Your hatch opening, cargo-floor footprint or loading geometry is too tight. The larger interior is not an advantage if you cannot load and secure the kennel correctly.
Impact Collapsible Dog Crate 30-inch — Black
Best for: folding storage and repeated transport when collapsibility matters more than named crash-test certification
The Black 30-inch Impact Collapsible Dog Crate has a stated exterior of 30.5 × 20.5 × 26 inches and weighs 28.5 pounds empty. It uses aluminum construction and folds between uses.
Why it works
This model addresses a different constraint from the two rotomolded kennels: storage and repeated handling. A folding format can make sense when a permanent crate footprint is impractical at home or in the vehicle.
What to check
Confirm the exact usable interior dimensions before choosing it for your dog. Check the 26-inch exterior height against your hatch and in-vehicle clearance, and follow the manufacturer’s restraint instructions for this model.
Skip it if
Your buying decision depends on a formally crash-tested or CPS-certified configuration for this exact collapsible model. Folding convenience is not a substitute for that evidence.
A Vehicle-Fit Check Before You Order
- Measure your dog’s required usable crate space.
- Measure the narrowest hatch or door opening, including the angle needed to maneuver the crate.
- Mark the crate’s exterior footprint on the cargo floor.
- Confirm the hatch closes without contacting the crate.
- Check which way the crate door must face and whether the dog can enter comfortably.
- Confirm the exact restraint kit and attachment points required for any safety claim you are relying on.

Frequently Asked Questions
Can I choose a dog travel crate from my dog’s weight alone?
No. Weight does not establish usable interior fit. Measure your dog and compare those measurements with the exact crate’s interior dimensions.
Why measure the hatch if the crate fits the cargo floor?
The opening can be narrower or lower than the space where the crate will sit. You also need enough room to maneuver the crate through the opening at the required angle.
Does a CPS claim apply if I use different straps?
Do not assume so. The certifications discussed here identify named crate-and-restraint configurations. Evaluate the exact setup behind the claim.
Is a collapsible crate equivalent to a crash-certified crate?
No. Collapsibility describes storage and handling. It does not establish crash-test status or independent certification.
