We had a similar experience a few years ago. My wife was driving when a dog ran out from behind some bushes. There was no time to do anything but hit the brakes, and we heard that sickening thump and realized the dog was hit. She pulled over and luckily we saw the dog running away. It ran into a neighboring yard so we ran the bell to tell the owner. The owner came out and we looked at the dog and hew as fine, but what got me upset was when the owner said that the dog always runs out. The guy lives on a very busy road, next to an exit ramp from a local highway.   

In my estimation, this guy is guilty of animal abuse. Sorry, but I feel the same way about people who let their cats roam free in urban and suburban areas. Domestication brings changes and the pet owner needs to take responsibility.
