> I'd do my best impression of a dog for you...

A better comparison - you're a member of the https://en.wikipedia.org/wiki/Actors%27_Equity_Association, the part which you auditioned for says "dog", and the script & stage directions are within general AEA guidelines for animal parts.

I've only volunteered in museum work - but there are obvious social rules about interacting with wealthy benefactors, and I'd assume that any competent employer in this space is carefully screening for comfort and skill with those rules.

(BTW, "wealthy benefactor" is very much a pay-to-win system, with tier after tier of "just how many $thousands did you graciously gift us with this year?" reward levels.)
