Blue Boy is a cute puppy that is superb at training. He's bright and catches on super quick. Our puppies are all very calm, so dont think he's a jack russell. He's quicker than the other puppies and scores high on the temperament test for confidence and staying on task. He will be easy to train. He will also be calm, happy and affectionate like all of our puppies are. What makes him unique is his bright mind.
