Two weeks ago we got my wife's dog in house after it lived with another dog and slept in a crate with that dog for 9 years.
Obviously we didn't sleep that well for the first few days. Now our dog is settling down, but he still does wake up and bark at night every now and then.
What we tried is having a cuddle in the crate for him and a t-shirt of my wife (he sees her as his boss.)
But he still whines and barks at night.
I assume he's missing his mate.
Do you guys have any tips to get him to sleep/be silent until I take him for a walk?
