Sorry for those of you struggling with settling and crates - when Sweet Dog was small, settle was the hardest to teach, because he got so excited by being rewarded (face palm)! The crate was easier, just because he seemed to trust us and still, just accepts where we put him! (But let's not talk about his recall!).
Our big advantage with Sweet Pup is that our bloody brilliant breeder had crates all over their living room, in addition to the whelping crate, and the pups just wandered in and out all day, so when he came home and saw a crate, he already knew that was a safe space and went straight in. We feed in the crate with the door open, and encourage him in if we need to open the front door, and he has the ultimate inducement - the cat likes to sleep there, and he lurves the cat!
Anyway I crashed at 8:30pm last night, so DH brought SP to bed. Made it to 4:10 am, then another sleep (for him) until 5:40. It's also tough if your other half isn't on side. My only complaint about DH is that he has to be reminded to do training when he's in charge as SP is generally quite chilled.
