How aweful, those people must be devastated! I have never been able to understand why people would want other people's dogs, it just doesnt make any sense. It's the same here though... we are on gaurd when we take the girls out with us, we can't leave them out of our sight and i don't allow strangers to hold them!
I know people do leave dogs in cars, but that's one of the easiest ways for the boogy man to get to them
We never ever leave ours unattended in the car. If my son stays in the car with them, both my husband and i warn him... do NOT open doors or drop the windows and do NOT answer strangers. He is 14.
