Animal Care Needed - Full-time / Part-time

I'm looking for an occasional sitter for 1 dog, 1 cat. Walking my dog is required. Overnight care is required. Non-smoker. Looking for a person to care for our pets when we travel occasionally. June 19-21 would be the first travel time. Dog: Edward is a 9yr old, 88lb Great Pyrenes/Pitt Bull mix. He looks like a white Lab. Very gentle and sweet. He's mostly a couch potato but loves 2 walks a day. Cat: Jackie is a 10yr old Calico long haired domestic. Both animals are up to date with their vaccines/medical check-ups. Jackie the cat is shy and really just needs someone to make sure she has food and water - limited amount of interaction.
