Forget the child safety seat. If Pennsylvania State Rep. Tom Stevenson has his way, motorists will have to strap in Fido when they go for a ride. Stevenson has introduced a bill that would require that dogs in cars be restrained with a modified seat belt or placed in a carrier box. The bill would also ban dogs from hanging their heads out of vehicles. Stevenson got the idea from an 11-year-old who took part in his annual "there ought to be a law" contest.
