Mustang, it sounds to like he's just bored. I crate Daisy when I'm gone, but I give her a bone or Kong filled with peanut butter and sometimes left-over meat or kibble. I also leave the radio on for her. That keeps her busy for a while, then she sleeps the rest of the time.

I get my bones from the butcher shop and boil them before I give them to her. After she's finished, I still use them to fill with pbutter and freeze so it will take longer to finish.
