If I remember correctly and I'm sure Ali or Judith will put me right if need be, to get your puppy to like it's crate you need to put it's food in there to begin with and give him treats to eat in there with the door open to get him used to going inside. Then if he falls asleep somewhere else, put him in the crate so he wakes up in there. Make it a positive experience so the puppy sees the crate as somewhere nice to go and will want to use it as a safe den. Don't use it to put puppy in as punishment for doing something wrong. When you go out or bed time, make sure puppy has been exercised and toileted so they are tired and leave them something to chew which is safe to leave them with.
That makes it sound easy, I bet it won't be when we come to getting Mazy in her crate.
Mandy, the puppies all look gorgeous, hope you find out which puppy you'll have soon.
