Happens all the time around where i live...coyotes & foxes takes lots of outdoor cats and smaller dogs.

This winter 13 dogs have been taken by wolves in my area--that's just the confirmed wolf kills, many others have simply vanished. The wolves have come into musher's dog yards, people's fences. It's not just roaming, loose dogs this year. Last week my neighbor told me he caught three wolves "arguing" with his dogs through his fence at 3am.

I think these things will continue to happen and happen more often as humans continue to encroach on wild animals' territory.
