Pet Sitter - Full-time / Part-time

Looking for someone to assist me with a new puppy on days I work longer hours. I would like someone to come by on a weekly basis to spend 30 minutes with the puppy. Let her out of her kennel, take her to mess, and play with her. I also have a senior dog who takes time to warm up but may enjoy being let out in the back yard. Ideally this person would be able to serve as a dog sitter in the future as needed.
