Desperately seeking Rover
It's a wonder that a site like this didn't come along sooner. FidoFinder.com, in operation for about a year, is a place where pet owners can post and search for their lost dogs, as well as share related resources. A true Web community hub, it even has RSS feeds naming lost and found canines.
One word of caution: The site's operator warns of recent scams that have tried to dupe some registered members into paying ransom to con artists claiming to have their dogs. "Internet users must be careful as old scams evolve to the digital age," it says.
