Restraining your pets is as much about your safety as theirs. If a vehicle brakes heavily or is involved in a crash, an unrestrained pet—of any size—hurtling through the cabin can be a dangerous projectile that risks injury to human occupants and to the animal.

Even those labeled “crash-tested” are usually based only on each manufacturer’s claims and not indications that the products meet a standard requirement.
