I am laughing myself sick over your story. I can't help it. It sounds so familiar. I have to tell you, when I got Max, he was 5 months old. I flew into Memphis, rented a van and drove into Arkansas to get him, then drove back to Memphis, spent the night and drove back to FL the next day. When I left the breeders house, it was dark. We did not get 1/4 of a mile down the road and I had a 5 month old wolfhound sitting in my lap, while I am trying to see, steer and get him off me. He had no manners and knew nothing. What a fun trip home that was. Now, the only problem I have is Jake. He thinks he should sit in the front passenger seat whenever we go anywhere. If I don't have anyone or anything there I will let him, but when I do, I let him get in the front door and hop up into the seat. If I put him in the back, he has to stay there. Usually a hard shove into his chest and a really loud NO is enough to stop him. We take the dogs to Petsmart every weekend, but usually in my hubby's truck. It is a little harder for him to crawl over the console in the truck than it is in my jeep, so it is usually not an issue. Good luck. At least he didn't try to eat the little dog. Jake would have.
