6mo (today) large mixed breed we've had since he was 15wo.
He has never liked being in the crate and we have worked to make it comfortable and for him to be as neutral as possible about it. We have him crated while we get ready for bed and he is getting to where, most nights, he doesn't cry at all and will sometimes even hang out in there a bit longer after we open it and release him.
He was starting to be okay when we put him in there (never more than like two to three hours as he got older to go to the grocery stores/errands), wherein he'd cry a little bit but eventually settle and nap.
I also have been working on getting him to hang out by himself while I leave to go fill my water, run out to the car, grab a snack, or go to the bathroom, etc. and he's been doing well with his.
We have a camera with sound to watch him while we're away.
This morning, we took him to potty, like usual, gave him crate snacks, like usual, and popped him in there to go to the grocery store.
He cried, barked, howled, thrashed a bit, dug at his bed and eventually kind of settled with some crying before settling and crying once every few minutes.
I thought maybe it was partially because he hadn't gotten a walk yet. So we went for a walk and got him tired and let him rest for a bit but when we had to go back out (since we only made it to the one store before).
We turned the TV on before we left this time to see if that'd help. He panicked LESS and settled quicker but was still much more reactive about being alone than usual.
Do we stick to the training or is something not working? Are training needs changing as he's entering adolescence?
I don't want to have to crate him forever when we go out, I want him to be able to be neutral when we leave.
Please help
