Wanted: Pet sitter, Polygono

I am looking for a pet sitter in the Polygon area. The services I desire are dog walking and feeding for part-time work. The dog (Barakos) is playful and pleasant with people. I do avoid kids, of course. He pulls on the leash and will 99% get into a fight with male dogs. Everything is fine with female dogs. I want someone to take him for a walk on Saturday evening and one on Sunday morning, and to check if he has food and water, as I will be away from Athens. I would like to be able to collaborate again on another such occasion. Thank you.
