Here's what I found on Popdirt:
'Anderson Cooper 360' featured a report on dogs who became homeless during Hurricane Katrina last year, and Cooper reported 'American Idol' season one champ Kelly Clarkson watched the program and adopted one of the dogs featured during the CNN report from the Pontchartrain Humane Society. A photo of the dog, a German Shepherd / Border Collie mix, also named Kelly, is available here.
Isn't that sweet? Just shows you again how caring our Kelly is!
Here are pics of the puppy:
