Chewing is the result of separation anxiety and being alone for too long. Why hats, shoes and remote controls chewed up? Because our human oils and odors are on them, the object reminds them of their parent, they love and miss us.
Dogs live in the moment, so don't scold them unless you catch them in the act of chewing up your best dress shoes.
What to do?
Coolwag daycare is a good option. We also offer in home training to overcome separation anxiety. One strategy we employ is the Better Alternative like a stuffed Kong. Or just manage it by keeping high value objects out of the way.
Rest assured, it is usually just an adolescent phase and will fade as they mature and realize that you always come back!
