That is so funny and cute Doll!!
When my Yorkie was about 4 months old she was sitting in front of the oven door. She started to growl and bark at "the other dog" looking back at her. I choose not to interrupt her because it was so funny to watch her scold "the other dog". She carried on like this for about 4 minutes pacing back and forth from the kitchen to the living room. Each time she came back she was upset that "the other dog" was still there and wasn't scared off by her barking!
