Looking For A Pet Sitter For 1 Dog In Eastham

I will be gone during the day for approximately 12 hours a day Monday through Friday. I have a 9-year-old pitbull mix named Rose, who loves all people. I would just like someone to walk her for an hour during the middle of the day so she gets some exercise and is allowed to go the bathroom. I live in a network of dirt roads so you can just take her out the door and walk. No need to drive anywhere. She is dog selective. So I usually bring treats with a treat bag with me to keep her on task (I will provide)
