Bounce From The Back Of A Truck

I have a friend who has a large black lab. He didn't think anything of it and let her ride in the back of his truck, she jumped out trying to chase after something and hurt her paw. He tried for years to find a solution other than amputating her leg, but it would never heal properly. Eventually there was no choice, which broke my friend's heart. The dog is happy as can be now, happier than limping around with the bad paw even. While this isn't as bad as the accident in the original post, I hope people realize how dangerous this can be. If you know anyone who lets their dog ride in the back of an open truck, please warn them!
