I am going to tell you what happened here last night. Wolfie's reaction to the situation scared the daylights out of me., and has been on my mind since. I am wondering if I should be concerned or feel secure over his reaction. To tell the truth, right now, I am a little of both. Last night, while hubby and son were at work, I put Wolfie in his crate, while I ate my supper. There was no tv or anything on, just the lights over the kitchen island, and Wolfie's light downstairs. Wolfie started barking like a maniac after being in his crate for 10 minutes. Sometimes he does this as a way to get attention when he wants out of the crate. Figuring that's what it was, I continued dinner, cleaned it up, and went down to let Wolfie out of his crate. I barely got the second latch undone, when he came bursting through the crate door, hackles and tail up high, and barking ferociously. He headed for the outside door, which is about 20 feet away like a freight train and with such tunnel vision like he wanted to kill whatever was on the other side of the door. He didn't even slow down when getting close to the steel door. He went full speed jumping into the door, barking, snarling, growling, and clawing at the door knob like he was possessed. Then he raced up the stairs, with not a look at me, and went to all the doors trying to get out, still going nuts. I turned the floodlights on in the yard, and called hubby,who was about 20 minutes away. Seeing nothing at all outside, I got the big police flashlight, and took Wolfie outside. There were fresh footprints in the snow where no one walks, but nothing else around. All the other footprints were iced over, but these were fresh. I shined the light in the woods, saw nothing, hubby came home and looked around, still nothing. What we think is that someone came through the back yard, tried the cellar door, heard Wolfie and left. While I am glad that he is protective at 1 year old, I was taken aback at the intensity of his reaction. I have never seen a dog go absolutely out of his head like that. His trainer said that she could see strong protective traits in him when he was 9 months old.
