Pick of the Litter: Meet the Dogs

Meet six puppies on the eve of their final evaluation – Tartan, a female black Labrador Retriever whose over-excitability could be her downfall; Tulane, a female yellow Labrador Retriever, whose "jumpiness" might stop her from passing evaluation; Pacino, a black male Labrador Retriever with a chill demeanor; Paco, a black male Labrador Retriever with a mind of his own; Amara, a female Golden Retriever being raised by four-time puppy raiser; and Raffi, a black male Labrador Retriever, who occasionally still chews on slippers. It's their last test before returning to Guide Dogs for the Blind for formal training, causing their volunteer puppy raisers to display varying degrees of nerves before the evaluation.
