I'd prefer MxF but I can switch it to a HeHim!))

I kind of prefer MxM for this plot. If you are ok with it that is!

Sure thing!

Franklin walked through the entrance of the prison and got himself checked by the front guards. Once that was done he walked to a separate room and clocked in for the day. He then checked a paper to see what he was doing for the day and quietly repeated it to himself to memorize it. Franky then walked out of the room and to the break room to get some coffee to wake himself up a bit more before he went to his first assigned area.

(Sure, I would think they would allow him since he is a service dog but Casper would just be in a different part of the prison.)

Once Franky had finished his coffee he began his rounds. His first stop was cell block H, which had prisoners with service needs inside. He approached the block, which was empty but with a few prisoners, and went to one of the cells. "Morning Casper," he says as he writes something down on the clipboard outside of the cell, "how are you and Olli this morning?" He looked down at the service dog with a soft smile then back up at the man.

Franky nodded and says, "Well that is what happens when you get put in jail. I'll be by in a little bit with some food for both of you once I'm done with my check ins." He then puts the clipboard back and waves goodbye before moving on.
