Michael has taken care of my dog Tess many many times--he's my go-to friend to take care of her, because she adores him, and she doesn't like anyone! She's very picky, has a strict diet that involves lots of elements and supplements, and likes to be walked a certain way--carried to a specific corner and then walked the rest of the way through the park. Michael is wonderful with her and I never ask anyone else to watch her. She's only 7 lbs, but I've seen him with huge dogs too and they love him just as much. Very responsible and considerate, and a natural dog-person!
