People always think I am crazy for having a jack russell as college student but it is not as hard as it looks. Typically, JTRs are thought of as a very high energy breed. They are bred for hunting mice and other ground pest and have even been known for going fox hunting. The breed is short and stalky and very smart.

Beau, however, is a jack russell mix which means he's only got some of the characteristics of a jack russell. He definitely has high energy moments but 90% of the time he is a chill guy. It's important to know he's got a working breed in him. Working breeds need boundaries, training and lots of communication. The most helpful thing to do is to teach them jobs that they can do. Because they were bred to work they need to feel like they are doing something at times or their energy will become destructive.
