Now that is impressive. The safety systems are all designed for humans and yet a dog in the backseat, who could probably not be properly secured, survived.
This looks like thinly veiled marketing, preying on the unreasonable lengths that dog owners will go through and the expenses they will incur for their animals...
...and yet I see those little dog test-dummies and I want to shove money through my screen despite the fact that I don't even own a dog.
We do this whenever our dog is in the car. This is nowhere near as good as what we have for human passengers. One of the reasons is that dogs hate to be restrained. So there's a leash. In case of a frontal collision, this would prevent her from flying out of the window.
In the case of the car itself flying, and possibly tumbling on impact, I don't think the odds would be that good, as the dog would likely impact against hard surfaces. Or other passengers. That's maybe the least of the problems though, if the car's structural integrity is compromised...
oh yes, please don't ever restrain a dog with a neck leash in a car. It's better to have the dog fly off the car and take their chances, than to risk a broken neck.
I bought a new harness, with the largest contact area I could find, specifically for car usage.
