This isn't strictly speaking a booby trap, because people were involved in scolding the dogs, but the spirit is the same. Well, today, one of the few cars that we see on our rather isolated, dead end road, came along, and Bear and Sam who had not had their usual daily exercise today for various reasons, RACED after the car which can only travel very slowly on our gravel roads, and I went nuts! Afterwards I frantically read through all my dog books and found a potential cure. I called a friend, drove to her house, sat in the passenger seat of her car (unknown car to my dogs) and had her drive slowly past our place. I kind of hid down low in the front with the door open and ready. When they came out running toward the back wheels, she stopped and I jumped out, raising all kinds of hell, alpha rolled everyone, screaming and carrying on!! The expression on their faces when they saw it was me coming out of the car was priceless! Anyway, we drove back to her place, borrowed another car and repeated it - this time they were hesitant but they still approached. Same thing. Sam ran and hid in the middle of a patch of yucca plants and Bear didn't know what to do or where to go. So, another car and one more pass. This time I was inside the house so the dogs could know I wasn't in the car. My friend was prepared to run out of the car as I had. Both dogs saw the car coming and plastered themselves against the front doorway of the house. It was very effective. Will repeat tomorrow with different circumstances. Just thought someone might like to know.... How to make the dog scared of you and cars congratulations brilliant method.
