If you feel you are imprisoning your dogs by confining them, do what I do. i take mine to dog park every Sunday for exercise and socialization. you could just as easily take them on hikes or what not for the same reason. Aside from exercise this is a great way to spend time with your animals and further your bond.Dogs are not "imprisoned". They are not wolves that "must run free". They are domesticated animals and should be contained, need to be contained.
