Have 2 - year old Labradoodle (Indiana Henrietta Jones, Jr - affectionately called Indy) and a 9 month old pure black mini Goldendoodle (Black Magic Woman - Magic). When my daughter comes home from college we also have a Golden Retriever - Wrigley. With the three dogs outside we call our yard Wild Kingdom - the way they play with each other and try to be the "big dog." Usually the mini is the most agressive - she has to be to keep up with the bigger ones.
