T & P's Mom - thanks for the info! I really think that Trevor could become a door darter but I don't worry too much about Andy as he is afraid of his shadow at times and I think the outdoors might seem like a scary place for him. The other day I was standing at the door and noticed some furry movement out of the corner of my eye. Assuming it was one of the dogs and without really thinking, I opened the door. It was Trevor. He didn't dart, but I got the definite impression that if the door had been left open any longer he might have decided to take a stroll. Maybe I will purchase a halter for him, (if they make them in his size ).
