Never seen a paperback version, but "The old man" or "Grandad" have worked out well for me. There's some hardcase bits in both versions, and some sad bits especially at the end of "Grandad". Maybe "Good Mates" will work out well for you.
Enough of the humour, I'm yet to find a book that'll help. Failing a book, YouTube is probably your best search. That and practice, goats are usually plentiful in most areas and share a very similar make up to deer.
