Bock bier is in the lager family. What yeast did you use, and at what temperature are you fermenting? The best thing for you to do is keep the beer as cool as possible during fermentation, transfer it to another carboy when the beer is finished fermenting and try to keep it cool for 4-6 weeks to simulate lagering. I'm sure the beer will turn out great, but it might be slighly different than a traditional bock lager.
