I am brought here by the fact that I have recently lost a dog to an eighteen wheeler in front of my house. She was an English Golden Retriever puppy, named Ellie, with champion bloodlines, going on a year old. She was very well trained-knew all the basic commands very well, knew many tricks, had a very good attitude, and was basically the ideal case. She knew not to go onto the road (to her that was only for when I had her on a leash). I had been giving her at least 2 hours of intensive training every day, even on vacation, since she was eight weeks old. She was worth (money wise) about $15,000 dollars. To me she was priceless.
It happened when she was doing counting exercises in the front lawn. I was having her bring the tennis balls back in the order I asked (like "3, 1, 5, 4, 2."). She looked up, saw the truck going down the road, and got a little crazy. She ran right into the side of it.
She had always been frightened of large trucks, and I had been training her to keep steady, but she had never even came close to moving toward one on purpose. Does anyone know what her train of thought was doing here, and how I can make absolutely certain this will never happen again?
