Growing by leaps and bounds

He is growing so big that we cannot keep him in his crate fulltime. We have to teach him to behave in our house as we have no room for a larger crate! We have been allowing him in selected rooms, one at a time, but today I did not barricade him and allowed him to roam the house with me for well over an hour. He was perfect! Well, almost… He did break a CD case, but the CD is fine. And he did grab objects which had to be removed from his mouth. He picked up a small glass chest filled with marbles and spilled them. But, he obeyed, “Sit. Stay,” while I picked them up! Now is that a good boy or what?!
