Thanks guys...yeah it's AWFUL, I can see how it could happen to anyone though, esp with smaller dogs. It's just tragic.
My dad said Tasha liked to sleep under the car in the shade, and that he called them both out from under the car before he left. Same thing every day....
As he was backing up, he said they were next to the car like they usually are, and then she just went under the wheel for whatever reason.
He's devastated, of course, and I am sad for him and Chelsea. Those two dogs have been with each other since birth, and I hope that she doesn't get really depressed or something.
