You have a couple options:
1) Use an iFrame to display the blogger site (easy, not ideal)
2) Publish the Blogger feed to the DNN site. Since blogger uses an Atom feed, not RSS, I use Feedburner to convert the Atom feed to RSS (it's free).
If you do that, you have a couple more options.
A) Use the news module in DNN to publish the feedburner feed (You can see an example at www.mpolino.com)
B) Use feedburner to convert it to HTML and use the Text/HTML module to publish the feel (It's a small piece of Javascript and you can see an example at www.dynamicaccounting.net)
I find that option A gives me more control over the layout but it can be a bit flaky and option B is rock solid but harder to get just the way I want.
A few things to be aware of on the blogger side, you need to turn on site feeds. If you publish a full feed, Blogger will occasionally hiccup and go back to a partial feed, despite the setttings. To fix this, change it to a partial feed, republish the blog, change it back to a full feed and republish the blog.
