That's what happens when you let your dog drink in your car.

I often drive with my dog in the passenger seat, as he's my best buddy. But neither of us drink in the car. I drive, and he sits there smiling and watching.

Since we're telling dog stories, here's one that illustrates how observant a dog can be. My previous dog (now deceased) also was with me daily, as I took him with me everywhere in the car as well. One day I was visiting someone where I left him in the car to wait for me for about half an hour. After about 20 minutes I heard a horn blowing. Since mine was the only car in the area, the person I was visiting asked me if it was my car that had the horn blowing. (On some older cars you don't need the key in the ignition to blow the horn.) I said "oh, that must be my dog". Hard to believe, but it actually was true. It WAS him. From observation my dog had learned how to blow the horn in my car without my ever teaching him that. And he knew it would get my attention. Smart little SOB... he was waay too clever.

Better keep your car keys where your dog can't find them.
