I see an Aussie every afternoon, Monday through Friday. Yes, she is bossy and oh so smart. When people tell me she is a sweet dog, I tell them that she is, but she can also act like a female dog! She knows how to work people and other dogs!
She will get into trying to outsmart me. She goes through streaks of misbehavior of different sorts. We have a 45 minute visit to the dog park, unless one of her or my friends are there, and then we might be there for up to 2 hours. She went through a period of time where she would hear my timer go off and would run away instead of coming to me or to the gate to leave. When dogs get in my car, anytime, they get a treat, a small piece of dried salmon skin. We had been having a few days of her resistance, and one day it was particularly challenging. I told her, "No treats in the car." I finally got her and we got into the car. She did not get a treat that day and she has never resisted leaving the park since. She is so smart, she doesn't have to hear the timer, she knows when it is about to go off and comes to me to put on her leash.
