I rescued Molly out of the Wasilla dog pound 3 years ago, She took a long time to settled down, as she had 3 owners before me her first year of life. I am sure it was because she likes to run. We have a nice fenced in yard for her and of course she is a house dog so she has the run of the house. She was chipped, tagged and housebroken when got her and somewhat trained. She has mellowing out a lot this past year. I can now walk her without pulling my arm off. UNLESS she sees another dog and then she goes ballistic. We are working on that one. She is a very sweet loving dog.
