Pet Sitter Needed

I have a dog that is not fond of strangers but once introduction is properly done you become his new best friend. I have chronic illness and while I am not in immediate need if for any reason I needed to be in the hospital or was just down with my illness, it would be nice to know there is someone he is comfortable with that can help with him if needed. I would of course pay for introduction get togethers same as the rate for time to walk etc. I dont have family in the area and he is a larger dog so the friends I do have Im not sure would be comfortable or able to properly handle him if a moment called for.
