Pet Care Needed - Full-time / Part-time

I am looking for someone to come let my senior dog out during the day while I am at work. He used to be able to hold it for 9 hours but now he is very uncomfortable and it's not healthy for him. He is extremely easy, I literally open the door, he goes out and comes back in. My schedule is a little flexible, I follow a local school districts schedule so no holidays or weekends, I will be home when I am sick, and some days I will send them to daycare. I also have another dog, who goes out on a tie out, we can talk about whether he is included in this or not. He can hold it better but takes a little longer to go.
