Start feeding your puppy inside the crate with the crate door open. After a couple of days, feed with the crate door closed. Throughout the day, ask puppy to go into the crate and toss a toy or treat in for her. Praise her for going in. After a couple of times, start closing the door with you being right there. Then work on longer times of being in the crate with you there, then with you in a different room. Praise for good behavior, use treats, and don’t respond when your puppy cries, only when she’s quiet.
