Not a good idea to leave pets or children in vehicles with the engine running.
So true. My Jack Russell Terrorist locked us out of the truck down in Georgia several years ago. I was pumping gas while my husband was in the store. I went in the store to tell him the dog locked the truck and no less than four guys jumped up, ran to their trucks, and came back with slimjims taking bets on who could get in first. We were unlocked in seconds, thanked them, and left. They were settling the bets as we pulled out.
Jacks...we have one partial. He lets the other dogs in and out when they are barking at the door. He is the scariest dog we have owned. He gets so much of what we say. He sets up trick situations for other dogs to get them to do things. And he has no shame.
