Who Let the Dogs Out????

This morning during breakfast Madelyn was sharing some details from her last P.E. class. She was telling Mary Kaitlyn and myself about a dance-off they had last week. She said that they got to do the song "Who Let the Dogs Out?" two times. Madelyn then went on to sing a little from that song. Several minutes after this conversation, Mary Kaitlyn so sweetly asked me "When do we find out who let the dogs out?" I did my best not to laugh. So, do you know, who let the dogs out?
