Three fits, not one
The dog needs enough room and correct restraint geometry. The crate or harness must physically fit the vehicle. The vehicle must also provide the anchor points and clearances required by the product instructions.
Measure all three before ordering. A large crate that cannot be anchored correctly is not made safer by being expensive.
Look for the test, not the word tested
Ask who performed the test, what standard or protocol was used, which exact size and configuration passed and whether the current retail model is the tested model.
Independent certification is more useful than a brand’s unqualified crash-tested claim. Read the test organization’s record and installation conditions.
Crates and harnesses
A travel kennel needs a strong door, appropriate ventilation, secure tie-down points and a location that permits the specified anchoring. Loose luggage around it can become part of the hazard.
A vehicle harness should control the body without relying on an everyday walking attachment. A long tether can allow dangerous movement even when it prevents escape.
The Canadian purchasing wrinkle
Heavy kennels can be expensive to return across the border. Confirm dimensions, vehicle fit, Canadian shipping, return freight and warranty handling before discarding packaging.
A reputable local retailer may be the better purchase even at a slightly higher shelf price.
Bottom line
Our present view
Choose independently tested equipment that fits both dog and vehicle, follow the exact anchoring instructions and keep the dog out of the front seat. Recheck fit and hardware regularly.
