Paris Hilton has reportedly dumped her famous Chihuahua partner, Tinkerbell, for another dog, Bambi. Apparently, she only likes Chihuahuas very small and Tinkerbell got too big, growing past her ideal weight of 3.5 pounds. Hilton is now under fire from many animal rights activists, including the organization PETA, for this action. A spokesperson from the group said, "It's a pity that Paris' heart doesn't match her pocketbook. Animals shouldn't be disposed of like last season's trendy handbag." Why didn't anyone stand up for Nicole Richie when she got dumped by Paris? Won't somebody please think of Nicole Richie?! Cue the over-dramatic bawling.
