More: Razzo is the sweetest companion, who loves his family and walks around the neighborhood. He's not a working dog, which is fine with all of us. But his breed was the (supposedly) the foundation for all present day retrievers, and the breed is currently known as truffle dogs. Razzo lives up to his "nose" but tracking the scent of any and all strangers in the house. It's quite cute to see him walk around the house and retrace the steps of anyone not family.
