This is Zuko, our Austrailian Shepherd / Flat-coated retreiver mix, we call him an "Austrailian Retreiver" and he is certainly the intelligent goofball. He knows No and Sit, and he is working on Stay, Come, and Race. Someday I hope to put him in some obedience classes to show off how well-trained he will be. I found that I am better with big dogs then small ones. Zuko has one ice-blue eye and one brown eye, it's a great conversation starter on walks!
