E-Z cheese

Mark had made himself two turkey and cheese sandwiches yesterday to eat on his way to the track meet. He came in to say goodbye to us with one in hand. When Mackinna saw this she decided she needed a piece of cheese, but Mark had already put away the block of cheese.  I suggested she grab a string cheese from the fridge, so when she went to the kitchen, we all assumed that is that she was doing, however shortly after, Mark goes to leave and when he grabs his second turkey and cheese sandwich, he notices something missing.  The turkey and cheese sandwich is without cheese.  When we asked Mackinna if she took Daddy's cheese from his sandwich, she denied it, but something tells me the dogs didn't jump up on the counter, eat the cheese, while leaving the turkey and then put the bread back on the top of the sandwich.
