Manners - doggie style

When Gracie was about 6 months old, we began our regular outings to the dog park. On our first few visits, I would point out things I thought she should know. For example, I explained to her that Border Collies were there to play ball or Frisbee. They would not think she was cute and play tag with her. I also explained that some German Shepherds can be very friendly, while others might be standoffish. She should proceed to introductions carefully. And of course, I told her that some boys just couldn't control themselves - neutered or not - and so if all else failed, she should just sit down and tell them to go away.
Of course, the best lessons were taught to her by other dogs. Her first lesson in manners came from three Cattle dogs who did not appreciate her Lab enthusiasm in their midst. Thereafter, Gracie would approach a group of dogs with a bit more deference, showing her submissive side until the unspoken "all clear" sign was given.
Gracie is not a submissive dog by nature, so learning this form of etiquette was a challenge for her. Now almost 3 years old, she will show a modicum of submission when first meeting new dogs, but it is clear that she wants to be in charge.
The only exception is with a dog name Hunter. Hunter is a beautiful Rhodesian Ridgeback. We see him mostly on the weekends when we arrive early enough at the park. Hunter has never made any aggressive moves toward Gracie, but when she sees him on the path, she sinks into full submissive mode. Her tails scoops under her belly, she bows her head and looks away. All 85 pounds of her seem to magically melt into a very small dog. She will even step off the trail. Hunter trots by her with barely a glance in her direction. Once he is several yards down the trail, Gracie is herself again.
I marvel at the complex social structures created by the dogs at the dog park. I'm sure there are lessons there for us humans as well.
