Today I saw a dog fall out of the open window of a pickup truck and bounce a bunch on the road, almost getting run over.
Luckily the dog could get up and run back to the truck that stopped, but who knows if it will survive.
Dogs are fucking dumb. They don’t understand cars or windows. If you have a dog and let them ride in a car with open windows without secure restraints you risk that they die or get injured (and injure others) and you’re an abusive asshole.
