barking

She is barking because she is lonely.  Dogs are social pack animals.  If a dog lives with a human family, the humans are now their pack.  If you throw your dog outside 24/7, you are doing a grave disservice to the animal.  This type of treatment is what results in a neurotic, aggressive dog.  I strongly urge you to make your dog a part of your family - indoors.  Take whatever training courses necessary to learn how to properly train her to be a good housedog and make her another family member.  If this is impossible, then please find her another home.
