I'm confused about which name you are trying to translate.
If you're looking for a translation or transliteration of Wolf, the Hebrew letters for a the animal wolf are this: זאב and the pronunciation is Zeev or Zev ( I think). However, read the following paragraph as the choice is of transliterated names is not rigid.
The translation of English or other languages names into Hebrew is not a cut-in-granite, formal sort of thing. Beresh or Baruch are both fine choices. Even and especially Binyamin is fine (Benjamin). Bernie and Benny are pretty much similar. It's his or your personal choice. However, but don't think it's a formal matter.
