When looking for a dog car harness or doggie seat belt system, do you expect them to have been safety tested?

They absolutely should be tested. If you plan on purchasing a dog car harness or other pet travel safety device for your dog, ask for testing results. The Bergan dog car harness is a brand which has been strength tested. PetBuckle has done actual crash testing along with strength testing - http://www.petautosafety.com/pet-buckle-dog-car-sa...

I would like to see/here about them geting teated makes more sence dont it....... What i do is put a harness on my dog and tie the leash to the seat.

Oscar sits in a doggie car set when I drive. I love it and others seem to enjoy it. Keeps him and me safe

Yes- they should be rated for the weight of your dog. Try Ruff Rider. It has saved my dogs life. The $ is worth it.

These folks swear their product has been crash tested

My dogs go into their crates when being transported anywhere, and crate is strapped down to the floor of our SUV or our RV.

Yes, i do. If humans get such luxuries, why can't dogs?

I use a crate.
