This did happen once as I was sailing away happily in the middle of the Ocean, no swimming wolves though:

Have also had it in the Plains.

That looks like it's on the coast of the plains, which technically counts as plains.

The nice things about the hunted event is you can normally just run away from it. It's not in your base, and doesn't stick around like an event at your base does.

I encountered one coming out of the mountains recently that I didn't want to deal with, so I just kept going to my sea-side shack. Next morning there were only a couple of remaining wolves and lots of deer meat and such.
