How do I stop my puppy from crying in the crate during the day?

Before ever closing the crate door, get the puppy comfortable simply choosing to go in and out freely, tossing treats inside and letting the puppy explore at its own pace. A puppy that already associates the crate with good things before the door ever closes adjusts far more easily.

Close the door for just a few seconds while sitting right next to the crate, opening it again before any crying starts, then gradually extending the time and your distance as the puppy stays calm. Rushing this step is one of the most common reasons crate crying becomes entrenched.

Letting the puppy out the moment it cries teaches that crying works, so instead wait for even a brief pause in the noise before opening the door. Avoid using the crate as a punishment at any point, since that undermines the positive association you are trying to build.

Days 1 and 2 can focus purely on open door exploration and meals in the crate, days 3 and 4 on closed door sessions of a few seconds up to a couple of minutes while you stay in the room, and by days 5 through 7 many puppies can manage 10 to 15 minutes with you moving in and out of sight, always building only on genuinely calm sessions rather than a fixed calendar. A puppy that needs an extra few days at any stage is not behind, it simply needs a little more repetition before moving forward.
