Mine was the same way! I got her interested in some treats...something really tasty, like cheese or a hot dog (cut up, of course). First lead your pup into the crate with the treats and praise her when she's in there. Only give her those treats when she's in the crate...she'll learn that she gets the good stuff in there. Then, turn the tables on her...show her the treats, throw them in the crate (close enough to the door that she can smell them), but close the door so she's outside the crate trying to get inside to get them. Wait a minute or two then let her in there to retrieve them. I did that twice with my dog (who whined so much in her crate she made herself hoarse) here was the result...literally a day or so later:

she stays in there with door closed as well, but this proves that she now goes in there voluntarily.
