In obedience class this week, this German Shepard tried to attach Zoe. We were all sitting there listening to the instructor and then the thing went crazy growling, barking, and lunging. Of course Zoe was oblivious, just sat there and wagged her tail. The owners are an older couple and I question if they can really control this dog. The instructor is pretty good, and I trust him would not let anything happen, but it scared both me and my husband.
