I agree that it is a breed thing, but seems to vary greatly between individuals. My friend has a young male who is affectionately known as slobber chops as he is the most slobbery dog I have ever known, whereas my girl hardly dribbles at all. With regard to eating poo, this is known as Coprophagia. There is a recent topic under the feeding section entitled Change of Food to Stop Poo Eating, which might prove helpful.
