Free housing for dog-sitter July 18 - August 9

We live in a house on Stanford campus and are looking for a dog sitter for 3 weeks this summer in exchange for free housing. We're looking for a very reliable person who will live in the house while we are traveling - dates must match exactly. Our dog Maple is an extremely cute and friendly rescue, she needs to be fed and taken out several times a day and taken on 2 mid-length walks (1/2 - 1 mile). Please provide two strong references.
