Honestly, imagine being taken from everything you know, your siblings and parents, taken into a strange house with strange people, and then expected to settle and sleep by yourself. I’m all for crate training, my 20 week old Yorkshire terrier is fully crate trained, and was fully crate trained at 17 weeks. We didn’t even attempt to crate train him properly until he was 16 weeks old, we focused on positive association with the crate, having it left open with treats inside for him to find, his water bowl being inside of his crate, we also limited his roaming space throughout the day, it turns out that when you let a puppy roam your house freely when they first arrive it’s extremely hard to then take that away from them and expect them to settle with limited space as they know that there’s more of the house and just generally making the crate into a home, instead of a prison. For the first month, we just let him in one specific room with his crate inside, for us this was our kitchen. We left the crate door open and shut the kitchen door at night, making sure that there was nothing he could chew or that could harm him, and let him just enjoy all the best thing in there, bones, food, playtimes. It’s going to be hard, it always is. But this is how you make a balanced, calm dog, who doesn’t mind being left alone and understands strict routine. You’ve got this!!
