4 yr old female blue nose pit bull in York, Pennsylvania For Sale

I have a four yr old blue nose pit bull, she is up to date on her shots, crate trained , raised around kids cats and other dogs. The reason I am looking for another home for her is because she does not like my active house hold. I have three boys and when they have friends over or if I have guest over she gets very anxious and passes the floors. I have tried several things and nothing is working, so I feel it is best to find her a less active life style.
