Frozen yogurt can be offered to pets on a hot day as a cool snack.
Myths abound about feeding yogurt or cottage cheese to dogs because of lactose intolerance problems. Yogurt for dogs actually contains only a small amount of lactose and is generally well tolerated. Both yogurt and cottage cheese contain less lactose than milk, and the culturing process breaks lactose down into an easily digestible form of sugar.
