Anyone ever use this? or treat and train to help your yorkie be calm in the crate while you are not there?

I have tried frozen kong toys etc but he barks the entire day while I am at work. I know this because I have a dog monitor app that I watch him and have tried several different things such as leaving tv on, covering his crate uncovering his crate. he had settled down for awhile then suddenly has started barking again. He is 11 months old
