“he also employs a very competent personal doctor” - does this doctor have a name, or breed, or perhaps reference pictures? I would like to know… for reasons, lol!

Doctor Matteo Frosini, I imagine him as a fiftysomething Bracco Italiano from Florence. He has a dignified and collected look to him, but he can be surprisingly jovial and good-natured as well. Above all he's pragmatic, confident in his abilities and unflappable in a time of crisis.
