Layla is going on 9 months. I have not locked her in her crate now for about six weeks. She has been perfectly fine until recently. She has now ripped up a throw carpet. Chewed a pen she was able to jump up and grab from a table and has been digging up a huge indoor plant leaving soil piled on the floor. Her toys some of which she has had for months, she is chewing apart. Since she has had freedom for so long I hate to start locking her up again. Wondering why as she gets older, has this destructive pattern began?
