What can I do to keep my dog active or out of trouble when I'm not home? - Advanced Animal Care
Some dogs, no matter how much exercise you allow for them to get while you are home, can still be destructive. That's when crate training comes into play. But, if they have a toy that is fairly indestructible that they enjoy chewing on, you can give that to them. If you are able to take them for a nice long walk before you leave, you can get some of that energy out so that they're tired and sleeping while you're gone.

First of all, crate training your dog can be really helpful, or at least keeping them in an enclosed area where they feel safe. Within that area, giving them a food puzzle to do, as long as they have no food allergies, giving them peanut butter that's frozen and a Kong can be really great. Just things to keep them mentally stimulated while you're gone are great.
