These dogs need something to do all the time. If they find a backyard, excellent diggers will not stop until your yard is rodent-free. Their history of fox hunting has ingrained predator-like capacities in them. Most of the Jack Russell's are friendly, but they cannot be kept in a house with other small pets; this triggers their hunting instincts. They are vocal pets, and it is hard to win an argument when you don't speak their language.  Their dominating nature makes them not a great fit for a house with children. If you decide on getting a Jack Russell, then make sure they don't wander off on their own because other neighborhood dogs might be at risk.

These dogs have muscular bodies for their size. Their coats are of three types broken, rough and smooth, and they shed heavily. They are born hunters, so it is essential to channel their energy into positive growth, and training is crucial for that to happen. There have been cases of Jack Russell dogs being trapped in underground spaces, and we can attribute such capacities to their explorative nature.  They will not remain quiet in one position all day. Instead, they will try to bring the whole house down.

They are found to have high energy levels throughout the day and will need supervision all the time. You can't let them go out of your sight.

These dogs require at least 40 minutes of exercising in a day. Taking them out for long walks and hiking are suitable options. If you have a big backyard letting them run leash-free is another way to keep them fit.
