This website offers more than just training. It will also go over what to expect from a new puppy (do all puppies bite this much? he can only go 20 minutes without peeing - is that normal? etc.) in a new place (why isn't he eating every meal? is he drinking enough water? why is he sleeping so much? is all this normal in the first 2-3 days? etc.). They also go over how to introduce your pup to new surfaces and when to do it so they GROW and FLOURISH during their "fear" period to become confident, self-assured dogs instead of timid/anxious dogs. We get them started on this while they're with us with Puppy Culture, but it's important to continue when they go home! The first few months they're with you are still very important for forming their personalities. 

They also have a great unit on preparing for your new puppy, including helpful checklists and so much more. Here's the link for more info: https://www.baxterandbella.com/learn-more
