Leslie, I am so sorry Kersey is putting you thru this. I am a firm believer in crates also. Shaianne was in the crate almost all the time while I was away. And Keegan spends her nights in the crate while I am at work and when we go to bed.
I am sure you are doing most of the stuff right. I totally sympathasize with you, needing a break from the dogs. I need that too, it doesn't mean we are bad moms just human. Also, Kersey is still a puppy I am sure, so that probably adds to the problem. Sometimes as soon as Keegan gets out of the crate she is like "OK, now what can I do?" And she gets into everything. The one day I had just had it with her and I just sat down and bawled and said "Why do you have to be so bad?" and "IF I can't handle you I can't handle kids!" She was just awful! Keep your chin up, and try to take care of yourself.
