Good reliable company for pet and house sitting. Not sure if it’s a chain, but great for local West Chicago burbs. It’s a bit of hassle to get signed up, give them a key and the entry interview process. 

Once enrolled just go on the app and request a wide range of priced services and times. They confirm, and leave nice daily reminders when they stop in. We use them when we travel and when my son can’t let doggie out during the day.
