Q. My puppy has a hard time staying by herself, she cries and chews her crate. How can I make her more comfortable being alone?
A. Crate training is an extremely slow process, so you should be taking baby steps:
First, lure her into the crate with high value treats and close the crate door, then toss several treats inside the crate. During this process do not make eye contact, speak to, or hand-feed her. Toss in more treats and stand up. Then, toss in some more treats and take one step away. Return to the crate, toss more and take a few steps away. Return, toss treats, take 5 steps away. Return, toss treats, take 3 steps away. The key is to randomly change up the length of time you are gone, slowly adding and subtracting seconds. Slowly work your way out of sight. Then, quickly return, and walk out of sight but stay out of sight a few seconds. Return, toss treats, walk out of sight a few more seconds, etc. Take it slowly.
Finally, when you let her out ignore her, don't make a big deal of it.
