I have a six month old Lab F1B. she is wonderful! She seems to be able to learn quite quickly in most areas of training such as no jumping, sit, stay, lay, No, fetching and returning a ball and others. My problem is she still pees upstairs sometimes, I have her crate trained, and thought I did everything the correct way in training her. I have read at least 4 different books on puppy training but can't figure out how to stop this habit completely. Any suggestions?
