The reason we're supposed to wear seat belts is pretty clear to most of us by now. It's to keep us from becoming human projectiles in a crash.
That's the same reason more and more dog owners are buying safety harnesses for their dogs. But, unlike seat belts, there is no independent testing of dog harnesses and no national standard.
The Center for Pet Safety hopes to change that.
Last year, the group selected four of the strongest safety harnesses intended for large dogs and tested them with a new dog test dummy on a track.
