Chewing
Dogs, especially puppies, explore the world with their mouth. She likes to chew because it calms her. But it destroys your stuff. Even worse -- she might eat something like a sock that could block her intestines. Break this habit now. Give her chew toys, and take away things she shouldn't gnaw on. If you catch her chewing something she shouldn’t, say “no,” replace the object with an approved toy, and praise her once she's chewing it.
