This is nothing new, but most people don’t know about it-
Wolf attack numbers and details are always controversial, and much of the information people find is very poor. This is one large study on-line (pdf), however, that is often missed.

I am reposting it because of the frequency of this question. If it is posted in more locations, it will also show up more in search engines.
