Cash - Introducing CASH - my Jack Russell Terrier dog. I got him last April 2011; he's 4months old now. They say that Jack Russells make a terrific family pet and get along well with children - but with cash's age, I doubt it! On my observation, he is always running around the house, messing things again and again, and staying in one place for a minute is an impossible task. Not that I am complaining though, ha-ha. He's young and he thinks he has the liberty to do what he wants, when he wants it and where he wants. I just wish that he grows as a happy, energetic, assertive and an extremely loyal pet dog I love you, Cashables! Mwuah! ^^
