We half crate trained but got rid of it when she was getting too big. She just stays in the living room at night and (probably jinxing myself now...) she's not destructive so is OK.
We're finally getting somewhere with the barking when being left as well 🥳 we can go upstairs for a longer time and she stays normally in a lay down until we come back. If she does a few barks she stops fairly soon after. Just got to crack the leaving at home on her own! She'll have a kong for a bit but then she'll leave it when she notices we've gone (filmed her the other day) beef tendons do tend to last her so we're going to try that next.
She's also started to let my cat come downstairs and have a wander around the floor without chasing him which I'm so glad about as a few months ago he was a very fun game. He's got steps that go around the room so he can stay in the room but out of reach and I think that's really helped her get used to him being around.
She's really turning into a lovely dog though so I'm dreading any teenage behaviours!
