My little DJ is 4 months old now, and half way through her 6 weeks of puppy training. Last night she totally surprised me. There are always people that stop to look at the puppies go through their training paces and watch through the windows that surround the training area. Never a problem....until last night. A man in a white t-shirt stopped to watch, along with several other people. There was nothing unusual looking about him--no hat, nothing unusual at all--but I think he must have made eye-contact with DJ, because all of a sudden, she got all stiff-legged, stared directly at him, and cut loose with one of those DEEP DOBERMAN bark-fests. That's the first time I've heard anything quite like it come out of her---it's always just been puppy-barks up till now. The man walked away, and I took a couple of seconds to calm DJ down and got her to stop barking. The owners of the other smaller pups in class were sort of wondering what was going on LOL....she was just being observant to the fact that a stranger, someone she didn't know, was actually watching her closely, and she was alerting me to the fact. It was a tiny bit upsetting that she disrupted the class with her actions, but at the same time, I was SUPER proud of my little doberman being.....well, a doberman.
