There exist over 400 Radioland bloggers who write about dogs. How did I find that out? I searched for them. Here are some tricks you can do with google. To exclude Dog News: weird, inspiring dog tales  from the pack and search all Radioland sites for dog news, go to Google's Advanced Search, fill in as follows: 

Find: all: dog 100 en
without the words: inurl:0107233
Date: past3months

Domain: only return from site or domain: radio.weblogs.com

Voila! Now you can search Radioland for other writers on your topics and exclude your own long winded news site. You can search within your own site too, even if it's on Radioland. Blogistan has a tutorial; so does John Robb, dws.FAQs and explanation of how to add Google Search to your website.  Google on!
