Puppies chew things. Some more than others. Labs chew a lot. Give her some things she can chew on. Kong chew toys are great. You can put peanut butter or doggie treats in them. That keeps them busy. When she chews things that you don't want her to chew. Tell her NO, then give her something else to chew on and tell her she's a good girl when she chews on her chew toys. I am not in favor of hitting or spanking dogs. When she chews on the wrong things and doesn't stop when you tell her no, put her in her crate for awhile but not too long. As she gets older she won't chew as much but she will always need to chew.
