We just got an 8 week old pup - a husky/collie cross. He has no issue with his crate during the day/when it’s unlocked, that’s where his food and water is and he even plays with toys in there out of his own free will. The issue begins when we lock the door, either to go out or to go to bed. He barks, yelps and howls and won’t let up. He stops eventually after a while to sleep but I’ve woken up in the middle of the night at 3am and he’s still yelling. He has no problem with the crate in itself, it’s being locked in it that’s the problem. I’ve tried locking him in and sitting beside it to see if it’s separation anxiety but that doesn’t help either, it’s definitely the fact he’s locked in. The crate is definitely large enough (I bought it in XL so he fits in it when he’s fully grown), I’ve put a towel in with the scent of his mum/siblings, and I’ve covered it over with a blanket to make it like a den. We let him out for toilet breaks 2x during the night and make sure he relieves himself just before we put him to bed. He doesn’t throw himself around the crate, just sits and barks/howls. Does anyone have any advice? He’s driving me crazy. I’m doing everything right by him but I can’t be with him 24/7, I need to sleep/shower etc. The crate is located in our kitchen as we live in a relatively small house and there is no space at all for his crate upstairs.
