TLDR: make it cold!
Obviously it will depend on your breed, but we realized puppy (now 3 months old) slept way better at other people's houses in the crate, vs in our condo.
She was 1 hour up, 1 hour down (crate), but occasionally she would sleep 3 hours or more (crate) when we brought her...
@ijesusafrica I have my first gsd and she's very chill once exercised (but I asked for this from the breeder), but we're navigating through teenage dog reactivity that I don't think I would've had with a golden or a lab.
Love the velcro dog part, but I put boundaries - I go in the washroom...
