Pet Care Needed - Full-time / Part-time

We are looking for a person who is caring and passionate about pets to come on a somewhat routine basis (every other Saturday) and on occasion to walk and potty our two small dogs. We are also looking for someone to house sit overnight and care for them a few times per year for vacations. Since they are small, potty breaks every 5 hours while house sitting. Generally vacations are a couple long weekends and one a week vacation.
