Companion Care Needed - Full-time / Part-time

I need adult care provider with experience. Our care concerns are: Companionship. Looking for a caring and compassionate companion. I need a weekend car given - Friday night to Sunday morning. The job is to stay at the house with my 18-year-old son and 12-year-old golden retriever dog. Most of the car will be for the dog - she is easy! Feed her twice a day and two walks. As far as my son goes. He is able to care for himself, I just don't want him staying alone bc I don't want him to have friends in the house. Must be comfortable with 18-year-old boys
