Sniff Your Own Butt

I am trying to turn Molly into a more sociable dog it it kills me and evidently it is going to kill me. I took her out for her afternoon walk this afternoon and we ran into one of the neighborhood dogs, Arlo, while I was out. Arlo's owner and I were standing there talking and I was already in the dog park, so I decided to invite Arlo in for a little "play date" just to see what Molly would do and how she would react. All Arlo did was chase Molly around trying to sniff her butt and Molly politely told Arlo to "sniff your own butt, mine is fine, thank you." Molly is just not going to be the sociable, congenial, life of the party I want her to be.
