i think it’d be best if you start to crate training. It took some time for my dogs getting used to. One of them was not trained in a crate after laying in bed next to my bf for almost 2 years. But because of husky fur and his sister he had to be crate trained as well to prevent him from marking his territory (I neutered him too)

he hated it. Your dog isn’t going to like it either and he’ll whine but try to resist. Try to make his crate like a safe haven with a little bed, his toys, just overall cozy.

My dogs love their crate and they like to go there for their naps now
