As one looks a social networking sites, I really never consider having a SNS for your pet.  In the article, Pets Need Pals Too – Prevention.com the author discusses a site known as http://www.dogster.com/ which is designed to help pet owners find friends for their furry companions.  After reading the article, the author demonstrates that the site is also effective in helping the owner locate friends with common interest.  As if we didn’t know that that is what the site was designed for.  I think I would freak if I came in and saw my wonderful Abbey (Golden Retreiver) sitting in the computer chair surfing dogster.com! :)
