However, I’ve recently been persuaded that having dogs loose in the car is a hazard not just to the dog, but to the driver. Training the dogs to stay in their area has worked for us for years, but that’s only because we’ve been lucky enough not to be in an accident with the dogs in the car. So I’m certainly not writing this article as a way of judging anybody, since I’m a little late to the car safety game myself.
It has become increasingly clear to me that it's not responsible to have the dogs
loose in the back of the car, even though they're trained to settle calmly.
- A loose dog can distract the driver. While this issue can be essentially solved with training, not everybody trains their dog consistently enough to really keep the dog from coming up into the front area of the car.
- A loose dog can be hurt or killed by the forces of an accident or even by evasive driving. In the event of an accident or an emergency stop, a loose dog can be thrown with incredible force into the back of the passenger seats. With a little bad luck, the dog could even make it into the front dashboard or through the windshield.
- A loose dog can escape once an accident is over. If a window is broken or if a good samaritan or rescuer opens the door of the car, a panicked dog can escape and run off. This scenario is more common than you would think.
- A loose dog is a danger to the passengers in the car. Even a small dog can cause injuries to other passengers as he is flung through the cabin by the forces of an accident.
Having been persuaded that I can no longer, in good conscience, drive with my dogs unrestrained, I’m thrown into the rather confusing world of potential solutions.
Let me preface my discussion of these things by saying that I don’t see an obvious winner, but there’s an amazing organization called the Center for Pet Safety that is currently studying these issues. CPS is a non-profit that is not affiliated with any major manufacturer of crates, pet barriers, or harnesses, and I’ve read all their published research and found it to be pretty tight all around. But, even though CPS exists and is doing great work, they simply haven’t had the time or the resources to compare all the different solutions out there to each other in order to arrive at a definitive answer. So for now, I fully respect several different ways people try to solve this problem.
The only common solutions I would advise against in all situations are putting a dog in the bed of a pickup and tethering a dog by his collar. The downsides of a pickup bed should be pretty obvious, and it's illegal around here. And as far as a collar goes, in the event of a hard stop or a front collision, a dog tied by his collar and leash will simply be killed when he is brought up short. So if you tied your dog by his collar in order to keep him from coming into the front, you need a new solution pronto.
The CrateThe most common solution for restraining a dog in the car is probably the crate. The crate certainly works to keep the dog from distracting the driver, and it would definitely lower the possibility that the dog will become a projectile in an accident or escape during a rescue.
However, CPS did at least one test of a dog in a wire crate, and the resulting video, despite the fact that it uses a dummy, is still a bit disturbing if your imagination inserts your beloved pet in place of the dummy, as my imagination did. The crate in question isn’t tethered, which is part of the problem, but the basic problem with crates is that they don’t prevent the dog from building a speed differential relative to the side of the crate.
What do I mean by speed differential? I mean that when you come to a sudden stop, the tires stop the car, but anything loose in the car will continue at whatever speed you were going until it hits something. In a controlled deceleration, the friction of whatever you or the dog is sitting on is enough to keep you from sliding forwards. However, in a sudden deceleration, like an accident or simply full braking from a high speed, we need seat belts to keep us from flying forward.
So in a crate, a dog has chance to build a pretty significant speed differential before hitting the side of the crate, as you can see in the preceding video. While the crate almost certainly keeps the dog safer than being loose, this issue means that the crate may not be the safest option out there. An airline-style crate might be better than a wire one in terms of sustaining impacts more safely, but there simply isn’t clear data available on the crashworthiness of different styles and brands of crates. Either way, be sure to tether it to strong attachment points in the car with non-elastic straps.
The BarrierYou can also purchase barriers that keep your dog in the cargo area of your car. This option, like a crate, does keep the dog from distracting the driver, and it also keeps the dog contained if the door is opened by a rescuer. However, it leaves us with the same speed differential issue as the crate does.
The HarnessAt first glance, harnesses might seem a good all-around solution, but in 2011, CPS actually crash tested a number of car harness brands. Every single one failed. Again, the videos can be a bit disturbing if your imagination vividly puts your dog in place of the dummy. And remember that these are harnesses designed and sold as car safety harnesses, so any typical dog walking harness would presumably not hold up to the stress of an accident and would be little better than tethering a dog by his collar.
In 2013, CPS again independently tested a number of harness brands, and this time they released the names and detailed results. The only brand that performed acceptably was the Sleepypod Clickit. Some brands failed pretesting because they came apart when stress similar to a dog in an accident was applied, and those didn't even make it to the crash test!
Then, most of the brands that passed the pretest failed outright during the crash test by coming apart under the forces of the crash. Only the Sleepypod, the Klein Metall, and the Ruff Rider harnesses held together properly during the crash test, and only the Sleepypod harness actually kept the dog in the seat.
As far as I can tell, the biggest problem with the Klein Metall and Ruff Rider was that their tethers were too long, so the dog slid out of the seat and gained a lot of momentum before being brought up short by the harness. So the Klein Metall might be fine if you shortened the tether portion to 6”, since it offers an adjustable tether, but the Ruff Rider's tether does not adjust.
CPS also noted that the Sleepypod controlled the rotation of the test dog better than the Klein Metall, so that seems to be an advantage too. The last vote in Sleepypod's favor is that the company actually improved the design of the harness after examining CPS's crash test data. You can see a crash test video of the improved harness at the bottom of the 2013 harness study results page.
Page ten of the 2013 CPS report (PDF) has a great chart comparing the performance of all the harnesses that made it past the pretest.
The TakeawayWhile it’s pretty clear that I’ve personally settled on harnesses as the safest option for our dogs' safety in the car, I want to stress that I think the jury is still out. There simply hasn’t been enough testing done, and with the huge ranges of sizes and personalities in dogs, different solutions may work better for different families. Even though the early data suggests to me that a harness in general and the Sleepypod harness in particular are the best choice, that data doesn’t account for all of the real-world issues that may arise.
For example, the Sleepypod performed best on a dummy. In reality, it might be cumbersome or uncomfortable. It might sit nicely on a dummy, but still allow a real dog to pull out a leg or otherwise squirm in such a way that it's ineffective in a real accident. It may be so inconvenient to put on or to attach to the seat that it's impractical. It's hard to say without testing it on your own dog.
So if you do decide to use a harness with your dog, consider getting it from someplace with easy returns, or even from a place that allows you to try it on your dog before purchase. And don't forget to acclimate your dog to it before using it. If you spend a few minutes teaching your dog it's fun to get in and out of the harness, he'll have a far better experience when you expect him to wear it for a journey.
Lastly, remember that tether length played a key role in the crash tests. The harness does you little good if the tether is long enough for the dog to gain a lot of momentum or even to hit the seat backs in front of him.
Large-sized Sleepypods are backordered right now, but look for some high fashion photos of Golden Retrievers in car harnesses in the coming weeks!
