Pet Walker - Full-time / Part-time

I am looking for someone to live in and be available to dog sit my Rottweiler who suffers from severe separation anxiety. You would ideally be a writer, computer coder, work from home. You would not be responsible for Wally when I am around, only when I go out or am traveling. In exchange you would get your own entrance, bedroom and bathroom, living room area and some pay to be determined. You would be responsible for hiking/walking him 2x daily. You must love dogs and be comfortable handling a large 120 lbs. animal who is very friendly and well trained.
