Oddly, since I have studied Tudor history for years, I have just come across a bizarre anecdote floating around the internet. I wondered if there were any factual evidence for it, beyond dog-afficionado websites.
The story goes that when Cardinal Wolsey traveled to Italy to plead the annulment case to the Pope, he met with said Pope and they were just about to reach agreement on the annulment. Wolsey's greyhound Urian, who (probably in defiance of every protocol in the history of time) had somehow been included on the guest list for the meeting. As Wolsey knelt to kiss the Pope's shoe (again striking me as odd; this was not the normal way of saying "thanks a ton" even to the Pope), Urian freaked and bit the Pope for being too close to his master.
My understanding (flawed though it may be) was that Wolsey never even got to meet with the Pope in person, given that whole being-besieged-by-the-emperor nonsense that made personal audiences impractical, if not lethal.
I am, of course, familiar with the popular story of Anne's hunting dog Urian killing the cow, and Henry reimbursing the farmer. I am just having a lot harder time buying the idea that the entire Reformation sprang from the Pope being bitten (and thereby offended) by a dog who evidently missed one too many obedience lessons.
Any reliable sources?
