The Brooklynn cab driver dog was a bit of Faux Pas in Skyrim. I think it all depends on the province. I'm not saying the dog should have came from downtown Imperial city market district but any accent with a little sophistication or insanity from anywhere can work. Wes Anderson is he not american? He did an amazing job or the Sheogorath.

Modern American accents for an ancient fantasy word looses immersion points for me.
