The Jack Russell puppies are bold, happy and energetic dogs that love being around people. Because they have a lot of energy, you need to give them the right amount of exercise and mental stimulation for them to be truly happy. Jack Russel might not be the best family dog as they need to be in the right environment. However, if you are working from home or have at least one person in your family will stay at home, they can be a great choice for you.
