Sitter Needed For 2 Dogs In Belton

We are looking for basically in home day sitting for our older dog Jake, he is 15 and has a condition called LARPAR where his larynx is paralyzed and he has trouble breathing. This is made worse when he gets excited to the point were he could go into respiratory distress. He tends to get excited when left alone for period of time. There is not an option for day sitting on rover, so we are exploring how to accomplish this while we have to take some work related trips and only one of us will be home. is there a way to work out a 6 hour sit period? If not how close together can in-home visits realistically be? Thank you!
