Yes it is! Although, I don’t want to blame a whole breed of canine, I think that you need to teach your dogs to be better drivers.
The story is that back in the 90’s we were on our way home from a weekend at Lake Havasu. It was Sunday night, and on our way out of the park I made a quick stop and jumped out of the truck to leave my payment in the office drop box. Timo was following in his mini van loaded up with the family and all his stuff. There was no room for the dog, so he was riding with me. As I wed running for the drop box I heard Tim yell. As I turned around I saw my truck driving off across the parking lot towards other parked cars and the base of a solid rock cliff. We tried to catch up but couldn’t. Luckily, the dog missed the cars and stopped the truck before it hit the cliff wall. The bad thing was that he avoided the wall by running into a huge boulder. The dog survived completely unscathed. The truck, however, was declared a total loss. Since that day, I have never left one of Tim’s dogs alone in my vehicle.
