We leave the leashes on in the car, just in case we're in an accident and the dogs somehow manage to start running away. It's going to be easier for a stranger to catch a dog on leash than off if we're unable to go after them.i never leave a leash on my dog while it's the car. if my dog has to be in the car longer than 5 minutes
i take his collar off.
I'd like to think that the dogs would stand right by our bleeding comatose bodies and protect us... and that the news media would pick up on the story resulting in the state awarding medals of honor to the dogs and TOTW giving us free dog food for life...and then maybe a movie deal...But on the off chance that the dogs do run, leashes stay on.
