There are 16 books in total so i would assume, if viewing figures are favourable, there ought to be plenty more.
I watched the final episode the other night and, without spoilers, it is one of those endings where, even if there are no more to be made, it's still quite satisfactory.
Pasta and Wolf, if the subtitles appear, do not turn them off. If they don't appear, then turn them on. That's because there are some scenes spoken in French/Canadian and some of the indigenous characters break into their own language from time to time.
