No, thank you for your time! It seems to be at nothing in particular. He'll be laying in his crate for 30-60 minutes and then he starts whimpering. That quickly turns into a bark. We've tried ignoring it and it escalates into hours of barking, just the same as if we are stern and consistently tell him "no".
