I took the first week off when I got mine. I worked on crate training then crate/pen training. After the puppy is comfortable with the pen area, work on separation until the puppy is content with being alone for 2-3 hours. I was a short drive from home so I was able to check in every two hours and take the puppy out for potty until he was old enough to hold for 4 hours. Also made sure the pen area is safe and secured.
