Being a friend of Mark for many years made me realized that he is fond with dogs. I remember that he had a pet dog which he named brownie. I saw how he love his pet. He makes sure that brownie eats his food, walks with him, and grooms him everyday. Whenever we had a chance to talk, he never forget to tell me how he love dogs and how important Brownie is. I can see the admiration and happiness on his eyes when we talk about dogs. Mark is a perfect dog walker and sitter because of his motivation on taking good care of the dogs, and he will not let anything bad happento them. I can assure that Mark can be trusted and will be the best dog walker or dog sitter.
