answer:Jack Russells are very energetic and tend to bark a lot out of excitement. Take that into consideration when you are making a decision. And in my opinion, although several of our dogs love their crates and use them when they “vant to be alone,” 6 hours is a long time in a crate, especially for a young dog. Would your roommate be willing to at least interact with the dog and let him out of the crate and out to the backyard during the day when you aren’t home? And if chewing and peeing are a concern, you might consider an older rescued dog, especially one that has been fostered. You can frequently find pure breds among the rescues, although if you are like me you will find your heart held hostage by an FLM (aFfunny Looking Mutt).
