After 5 long years, we finally got another dog!!! We rescued a shih tzu mix from one of our shelters. Duffy was 5 - 6 months old when we brought him home on Sept. 1, 2015. We have crate trained him, however he is still not housebroken. I am lost as to what to do next and need some advice. Our yard is not fenced so we take him out on his leash and have a potty party when he goes along with a treat. Usually I take him out about every two hours and sooner after he eats. If I am busy doing something, he will potty in our living room even if I have just gone outside with him, I don't say a word to him and just clean it up and take him outside again. He has slept all night out of his crate for the past 3 months and has never had an accident. It's s like he doesn't know how to let me know when he needs to go outside. I taught him how to jump on the door and also tried the bells which scared him so I took the bells off. Look forward to your advice.
