More: Blue Heelers are often described as "buddy dogs" because they want to do whatever you are doing. When I shred the pastures - Callahan is right there trotting along the side of the tractor no matter the weather. When I study and write - Callahan is right there lying on the floor next to my desk. When a cow gets too close to my back - Callahan is right there shooing her away. He is my "best buddy."
