I was just wondering about the Corgi's ability to steal things. My dog is 6 months, and he loves to chew on clothes, shoes, and paper especially. He pulled a book off our bookshelf last night. Is there something to curb this behavior, or will it go away with age? Also, are obedience classes helpful? We have a Petco in our town and Petland. Our Petsmart is about an hour away.
