my 3 year old lab for about the last 6 months barks when people go to the bathroom in the night but only after around 4 am he does not get up until around 7ish. I have tried everything I can think of and nearly have a heart attack every night when it wakes me up and it disturbs other family members sleep who have to get up early for work. The things I have tried Ignoring him Telling him to be quiet calmly and shouting at him Letting him sleep out of crate Letting him out to see it's just family Letting him outside I tried these things all separate and for a period of time I have no idea what else I can do. He doesn't bark if nobody gets up and just wakes when I do.
