This article is from the Mastiffs Breed FAQ, by mmcbee@access.mountain.net (Mike McBee) with numerous contributions by others.
Most Mastiffs only drool when 1) they have just had a drink
of water or just ate, or 2) they are extremely agitated and
fearful, or 3) you are eating anything that smells better
than dogfood, and you have been foolish enough to feed the
dog some of your food at any time in the past.
Mastiffs with tighter lips tend to drool less. Experienced
Mastiff folks keep hand towels all around, to wipe faces
after every drink and meal, and other times as needed. If you
wipe the drool off immediately, it is a lot less likely to
get slung onto the dog's face or body, your furniture, you,
or the walls. If it makes you feel any better, 1) you get
used to it, and 2) St. Bernard breeders say their dogs can
hit the ceiling with their slingers, while Mastiffs tend to
only hit about waist height on a human.
Actually, if you are a habitual face-wiper it won't be bad at
all, but to be realistic, "spit happens".
