Pet owners in the US city of Santa Fe could be made to provide seat belts for their animals.
The city council says animals travelling in cars and trucks should be harnessed securely when travelling.
Kate Rindy of the Santa Fe Animal Shelter said: "Just like people need to be safe, so do animals."
Pet shops in the US already stock seat belts and portable pet carriers for cars but they say they haven't sold many so far.
Seat belts
A "pet safety sitter" has a strap that goes across a dog's chest.
A "pick-up tie-out" attaches to a dog's collar so it cannot jump out of the back of a truck.
You can also buy small "booster seats" which allow a dog to see out of a car window, while preventing it from jumping around.
