I would say this though, that when I was driving all over the state with two 90 pound labradors in the back of my Bronco, I was keenly aware that in the event of a wreck, I had two 90 pound projectiles behind me that would break my neck. I installed one of those mesh guards for that reason. From a safety standpoint, it's not good to have a dog loose in the vehicle with you.
Another useless law that the genetically deprived, the bewildered, and uneducated will endorse for their democrat pupeteers.
Never mind the dog sticking its nose out the window. how about the politician sticking his nose into everything we do!
