My Murphey is about 7weeks old and is being crate trained. He has done fine for up to 3.5 hrs. However over the past 2 nights he has peed in his crate. I have heard two ideas on the long night hrs. One is to set your alarm to get up and take him out about 1/2 way through the night. The other is to let him wake us up when he has to go, so that he does'nt get into the habit of us getting up everynight. I am interested in hearing from some of you that may have had the same situation.
