I am a potential borrower, I work ft and our house is tiny and we have young DC so getting our own dog isn't possible right now. I have just looked at BorrowMyDoggy and it looks like it could work well - I could walk early morns/evenings/weekends with the children etc.
Has anyone used the site? My problem would be that my hours are erratic so the walks I offer should be on top of the dog's daily requirement which might not work for someone.
