Britney Spears and Paris Hilton have done it, and so have many lesser-known Californians: They've tooled around town with pets on their laps.
Now, a California lawmaker is looking to get Fido out of the driver's seat.
State Assemblyman Bill Maze (R-Visalia) wants to ban pet owners from driving with animals on their laps. Last week, a bill that would do just that passed the state's Assembly Committee on Transportation. The state Assembly may take up the measure, which Maze wrote, next week.
Maze says pets are a distraction that could put motorists at risk, much like talking on a cell phone. In July, it will be illegal for the more than 30 million drivers in California to talk on a cell phone without a hands-free device.
If his bill passes, drivers who are caught with their Chihuahuas or calicos unrestrained will have pay a penalty. The bill does not specify how drivers should keep their pets in place.
"If you've got a live animal, which you're not able to control, and that thing gets between you and the steering wheel or underneath your brake pedal, you've got a problem," Maze says.
Not everyone is thrilled at the prospect of legislation, including Johnnie Bonds, who hangs out at a hilltop dog park in Culver City with his Chihuahua mix Shorty. He says he doesn't even like being told he has to wear a seatbelt, let alone his dog.
"The government should get out of my business, you know what I mean?" Bonds says. "Let me live my life my way, with what little freedom we have left."
Patrick Guilfoyle, who owns Double Dog Dare Ya, an upscale boarding facility in Burbank, says people don't realize how dangerous it can be to leave their pets unbuckled.
But at the same time, he understands how hard it can be to resist a freedom-loving pet's pleading eyes.
"They don't understand that dogs are at risk just the way a child would be at risk if they were unrestrained in a car," Guilfoyle says. "I am truly as guilty as the rest of them. I insist that they stay in the back seat, but that's as far as I've gotten."
The Society for the Prevention of Cruelty to Animals in Los Angeles has been lobbying for years to get the state Legislature to pass measures along the lines of Maze's bill.
"They can become projectile missiles during a short stop," says Madeleine Bernstein, president of the SPCA branch. "They can cause an accident. They can impair your ability to react to an accident. They can distract you. And they can get hurt."
If the legislation becomes law, Bernstein says, tails might droop a bit at being confined, but pet parents will have to draw on their inner strength.
"If you love your pet enough to take them with you, then love them just a little bit more," she says. "And restrain them when you take them with you in the car."
