Do you secure your pets when they're riding in the car? While most cats travel safely in carriers when they travel at all, the question typically draws an uneasy look and an uncomfortable response from even the most conscientious and well-meaning of dog lovers.

The truth is that most dog lovers – including those who wouldn't think of leaving home without first securing themselves and their children with a seat belt – don't provide the same protection for their dogs.

The results can be tragic. Unrestrained pets cause more than 30,000 accidents annually, according to the American Automobile Association, injuries and even fatalities that could in many cases have been avoided with the use of a restraint or carrier.

"It's beneficial to both people and pets to have animals properly restrained in a car – either with a commercial restraint device or in a carrier," said Dr. Tony Johnson, emergency department director at VCA Indiana Veterinary Specialists in Indianapolis.

"I have seen several dramatic and heartbreaking cases where dogs jumped out of a vehicle and suffered severe injuries."

Grant Biniaz of the pet health insurance provider VPI agrees.

"Injuries can be sustained during an accident, or even when slamming on the brakes," he said.

"We also see many cases where unrestrained dogs have been injured jumping out of an open window if they see something interesting – like another dog or a squirrel – outside of the car."

But it's not just about safety for pets. Restraining your dog while you're on the road protects people as well. Secured pets won't be the reason for a driver's distraction.

In the case of an accident, a secured pet won't be flying loose in the vehicle, increasing the likelihood and severity of injuries to all.

"In a 30 mph accident, a 60-pound dog can cause an impact of more than 2,700 pounds, slamming into a car seat, windshield or other passengers," said Christina Selter, founder of Bark Buckle Up, an organization dedicated to teaching pet owners about the importance of securing their pets while traveling.

"And if the animal survives and gets loose, it can run into traffic or impede the progress of emergency crews arriving on the scene."

There are many varieties of restraints, including harnesses that hook into the seat-belt systems, carriers and crates that keep pets protected and barriers to keep animals in the back, away from drivers.

In fact, one auto manufacturer, Volvo, has made dog safety such a priority that the Swedish automaker has introduced its own line of pet barriers that fit into some of its more dog-friendly models. Several other automakers are reportedly following suit.

No matter what type of restraint you choose, the key is to introduce it to your pet as early as possible, said VPI's Biniaz.

"It is very difficult to train an older dog to wear a restraint in a car," said Biniaz. "Pet owners should acclimate their pets to restraints from a young age."

The importance of pet car safety is perhaps best summed up by Sgt. Rick Martinez of the Anaheim Police Department, who has seen firsthand the tragic consequences of unrestrained pets in vehicles.

"We all want to spoil our pets," said Martinez. "The best thing you can do for your dog is to buckle them up in your car. In case of an accident, it will save their life and greatly enhance the abilities of first responders to take care of other occupants."
