Folks, let me be blunt. I have been a veterinarian for twelve years. I have seen hundreds of dogs that were struck by vehicles. This might be tough to swallow for those who have been in such situations, but it is the truth. Look in the mirror for the culprit when your dog is hit by a car.
Roadways are for vehicles, and are inherently life-threatening places for a dog.
I don't care if you have been letting him out the front door by himself every morning for ten years without incident. He, and you, have just been lucky. It is only a matter of time. I was fuming inside that these owners wanted to blame everyone but themselves for their negligence. Meanwhile Buddy has paid the price.
