The Retriever side of him that loves to carry, doesn't destroy, and has a job to do is fantastic. It is so different from Haddie who was not a carrier - and would look at me with a tone in her eyes that said, "Really?!" if I asked her to pick up anything off the floor that was not her red ball. I am not sure what the trick is to getting her to work-this in Advanced Training, but apparently she is doing it, because she has yet to be Released.
The Retriever-side of Kolby makes me smile.
