 Very little CGI is used in the movie, the only exception is the last  shot of the film which was considered impossible to shoot without  the aid of CG animation. The reason for this was because the  director, Craig Sratchan felt that contemporary cinema relied too  much on CGI and that traditional animatronics/puppetry FX were no  longer being used. He wanted to create a werewolf similar to the  beasts seen in American Werewolf In London and The Howling, both  of which used no CGI at all.
