Ok, here goes my "confine the puppy" lecture. If you've seen it already, skip to the next page.
Your puppy is just being a puppy.
It is very simple to prevent these types of destructive chewing episodes.
You need a good crate, and you need to put the puppy in it when you cannot supervise her. EVERY SINGLE TIME.
She will learn to love her crate, and you will be keeping her safe when you are gone. Some things puppies will choose to destroy can be dangerous for them.
Using a crate, she does not have to be shut off in some other little room where she feels abandoned and shut out. She can be in her crate in your living room with her own toys and bedding (if she does not destroy that)
Remember, that each time your puppy is allowed to chew in your absence, the behavior will be harder to modify, and will be MORE likely to occur again. These types of behaviors are called "self rewarding". No matter how you scold or punish, you can NEVER take away the stress relief, joy, and satisfaction the puppy got from chewing those articles.
Most destructive chewing takes place within the first 20 minutes after you are gone, and then the puppy goes to sleep. Puppies often choose things with your scent on them to chew, since this is comforting to them.
In large breed puppies, the need to chew can last as long as 2 years.
Get a crate.
Learn to use it.
Happy (and safe) dogs and people will result.
