Pet Care Needed

San Francisco couple needs a part time, regular sitter for 2 dogs in San Francisco. We are looking for a regular sitter to stay overnight with our dogs for a few longer trips this year (dates planned well ahead of time), as well as someone who can occasionally come during the day to play / walk the dogs when one of us is traveling for work (shorter notice, a couple times of month, may pop up a week ahead of time). We have a German Shephard and Javanese, 5 and 4 years old respectively. Looking for someone responsible that loves dogs. Both dogs are easy going, well trained, and like to spend time with people.
