Dog Sitter Needed - Full-time / Part-time

I have a very active 8y old miniature sznauzer. He's not the average dog that would let anyone pet him until the person earn his trust. He's very independent, drinks a lot of water, reason why I fill up a gallon of water every 2 days. There are doggy doors in the house, so he goes in and out by himself to the fenced backyard. He gets fed twice a day 10:00 a.m. and 7:00 approx. He is pretty healthy no special care at all
