Here's the best dog I ever had, for over ten years of happy times. Found wandering the streets of Miami. He came up to me and stuck to me, decided I owned him now, I guess. Immediately obeyed sit, down, heel, and followed without a leash.
Absolutely gorgeous coat, rust gold with a shepherd saddle and black eye-diamonds.
Polite, never an accident in the house, ever, and incredibly smart and well-behaved dog. You could leave a hamburger sitting on a coffeetable, come back, and he'd only be watching it closely, never, ever touch it. I think he was a shepherd-lab mix, since he had a shepherd bark and looked like one when his ears were up (I said he was an undercover police dog), but would sometimes point at ducks.
