Its obvious that coming to the decision to rehome Moxie was tough for you. I respect you for rehoming him and committing to check on him. A lot of people dump dogs off at the shelter. I don't know how much exercise your dogs get or what your training methods are. But I can tell you that Mac requires more exercise than I ever imagined. If I had a baby or even a full time job...I personally couldn't do it. So I understand how you feel. Take care.
