Why Mozzarella needs caution
Fresh mozzarella is milder than most cheeses: lower in sodium and moderate in fat. It still contains lactose, so quantity can upset the stomach, and a swallowed whole ball or large piece is a choking risk for a small dog.
Signs to watch for
Gas, loose stool; large pieces: choking or gagging
