My St. Bernard drools, not a lot, but when a dog weights 190lbs. "a lot" is a relative term! The drooling is mostly after he eats, and drinks. We keep a large towel handy, and just wipe his mouth when we notice he's visted the water bowl. If he shakes that massive head of his, slobber goes everywhere-on the walls, ceiling fan, you name it. If you don't cleanup right away, the drool can actually peel the paint on your walls.
All that said, the Saint is a beautiful, wonderful dog and a joy to own. He's the best for curling up with and watching a movie,or reading a book. He loves to go for walks, and never meets a stranger! Everyone is a friend he hasn't met yet, 'specially kids!!
