Calvin is cute, clever, athletic - in a puppy kind of way - and very much the charmer. He loves to meet new people and gets all soft and wiggly when he does. He does need a dog savvy family who can provide him with the necessary structure and guidance that he needs to become an ambassador for his breed. He could live well with another medium to large sized dog, but you should also teach him the joys of play with balls and tug toys rather than making other dogs his "play things." This will pay off as he matures, trust us!Meet Calvin at the Marin Humane Society or call the Adoption Department at 506-6225.
