Invest in the book "the pokey little puppy." It explains this dillema in full detail. In the book the pokey little puppy and his brothers kept digging under the fence. The others came home and didn't get in trouble, but the pokey little puppy always stayed out late because he would get curious and side tracked.
In the end, a group of pit bulls tore him apart and his carcass rotted in a ditch after being drug 30 feet by a 1989 Ford pick up.
(Okay, that really isn't the ending, but I didn't want to spoil the true ending for you guys)
