Siefkin (5 y/o), The Mission. Did you know that it costs 80K to raise and train one guide dog? This rad dude is doing his part to help Guide Dogs for the Blind. Because of his superlative qualities, he was chosen to be a breeder of future guide dogs. To date, Siefkin has sired over 60 future guide dogs, and it's estimated that he'll produce 200 puppies throughout his career. We're proud to call him neighbor.
