Pet Care Needed - Full-time / Part-time

Penn Valley family needs someone to walk our sweet Mini-Aussie twice a day every other weekend (Fri evening-Mon morning). Times are somewhat flexible. My mom watches him in her garden while I am away but shes elderly and its hard for her to bring him in and take him out. He spends evenings in her house. Give him fresh food and water. Would consider pet sitting at someone's house, too.
