I had a puppy once and she would bark up a storm at the two Great Danes in the fenced in yard across the street. But when the owner took them by our house for a walk- not a sound. The Great Danes, to their credit, ignored the pup and she turned out to be a great dog who got along famously with other dogs. So, Grasshopper-even annoying little puppies can become good dogs who play well with others if we just ignore their bad behavior and acknowledge that they have taken a submissive posture when the threat is real.
