Sam's mom says: Sam is a pure-bred Jack Russell. He and his half brother, Jack, both came from Holland. He is a total character and loves to make people laugh. He is always happy and looking for something to do. Sam is a Gemini, loves bully sticks, chasing leaves, and playing tug-of-war with his walking leash. He loves to burst into the bathroom when I'm in there (even though I close the door). But what Sam loves the most is to chase and bark at Jack when Jack plays ball with his mother (me).
