An unrestrained dog in a car is a projectile at the first hard brake — and for small dogs, the physics are worst of all.

Genuine crash protection requires crash-tested crates or restraint systems (look for CPS-certified gear), which cost several times more. Both are better than a loose dog.
The back seat, restrained — either tethered in a booster or belted via a harness — or a secured crate in the cargo area of a wagon/SUV. The front passenger seat is the worst spot because of airbags.
