After she’s willing to enter the crate, your next goal is to get her comfortable with staying inside for extended lengths of time. One of the best ways to do this (and create a positive association with the crate) is to start putting her food in the crate.If possible, you want to place the food at the back of the crate so that your dog goes all the way in. Some dogs may not be willing to do this, though, so you can start with the food just inside the crate and slowly move it back with successive meals.
Her situation is not unique. Your (and others)crate training procedure assumes that the dog has an established room where he’s used to hanging out with the family and that you’ve had him/her for a while. Bull! You have to start this procedure on the very day you bring the puppy home. Otherwise, the puppy will get used to being in your bed, will start a bad habit of peeing on the floor and learn that barking and yipping through the night brings rewards. Please update your method to show how it’s done on day 1, not over time!! Thank You.
Show it to the dog, let it smell and taste the treat, and then toss it inside the crate and shut the door, with the puppy outside the crate and the treat on the inside. That shows that an absolutely scrumptious puppy treat is inside, out of paw-reach. And after the pup has begged and scratched and whined to get inside, open the door and let it get the toy inside the crate. Allow your pup to chew and enjoy it for five minutes with the door shut and the dog remaining in the crate. Some pups settle down and enjoy their treat with no fanfare. Others throw a fit and want out. So if your puppy fusses let it out, but lock the treat back inside. You’re teaching the dog that wonderful things can be found inside the crate. Most pups learn to tolerate the door shut at least as long as they have something to munch.
