His name says it all. My roommate got Chance as a birthday gift. He is 7 months old and his jack russell traits are stronger than his boston lineage. very eneergetic and protective. But he has a mischevious side and very playful. The mischief is what gets him in trouble, like chewing on shoes or tearing up paper when he gets a chance. My roommate is ready to send him to the Humane shelter but i am trying to find him a good home.
