Congrats GF, Roo is a star. I have to admit that I am lax (okay that might be an understatement) at practicing our obedience work with the pups. It's just so darn hard to get one out and not the others. DH is no help at all. But that's okay, we'll manage, Nikki still gets it.
Shadow was attacked by a GSD when she was young and never trusted them her entire life. You wouldn't think dogs could distinguish breeds would you, but she could spot a GSD from a mile away.
