Dog car safety: harnesses, crates, and common mistakes
In a crash or sudden stop, a loose dog becomes a projectile—risking human passengers and itself.
Crates vs harness systems
- Crates work well when sized so your dog can stand, turn, and lie down, and when secured so the crate cannot slide.
- Crash-tested harness systems exist; marketing language varies—look for independent test data and follow the manufacturer’s vehicle attachment instructions.
What to avoid
- Collar-only leash attachments to seatbelts (neck injury risk)
- Front seat airbag zone for dogs in harnesses unless your vehicle manual explicitly allows a safe configuration
Heat
Never leave dogs in parked cars. Temperatures rise faster than most people expect, even in “mild” weather.
Ask your veterinarian if your dog has motion sickness—there are prescription options that are safer than human drugs chosen at random.
