How sad. I had two peke-a-poos years ago, mother and daughter, and they both would run up to people, barking like idiots. But that's all they did. Bark. I do recall one time, though, that a woman was absolutely petrified when my dogs ran up to her and they were small dogs. I can understand the police officer being frightened but it's the responsibility of the owners to keep their dog confined. Irresponsible pet owners and now a dog is dead. Shame.
