If you happened to see “A Few Good Dogs,” you will recall Granite, a leggy rat terrier with a signature stub tail, in the Tom Cruise role. Ears at attention, standout brows, a serious demeanor enhanced by undeniable cuteness, his performance was a Method masterpiece that happened to align perfectly with his off-screen personality. He’s a gentle and studious sort whose slight vision impairment means he likes a slow approach from dogs and people -– two species with whom he gets along very nicely. He’s polite, energetic, likes a snuggle and a soft place to nest. And he can handle the truth! Which, in this case, is that whomever adopts him is about to win the dog lottery.
