"The mother actually tried to hide the two kids," Clayton County police officer Phong Nguyen told NBC affiliate WXIA.
"There was a little dog in the house and it started barking so the intruders shot the dog. They demanded money and jewelry from the mother," he added.
The mother said she didn't have any cash of value "so instead they kidnapped the 14-year-old girl." Her 15-year-old brother was not harmed, police said.

Police said the armed suspects were driving a dark-blue Dodge or gray Chevrolet Impala.
