I think our next dog will probably be another Newfoundland again. We love the Saint Bernard we have now, but that is in part because Saints and Newfies are very similar in temperament. Of course they are very similar in the amount of drool as well

When we had our newfie in the condo, we'd frequently have to clean slobber slings off the ceiling. We helped reduce those occurences by only watering him outside.
Another benefit of a big affectionate breed like a Newf or Saint is coming home after a long night at work at 4am when the rest of the family is asleep and being greeted by a big (wet) bear hug from our Saint. Luckily I'm a big guy or she'd bowl me over (she is rather small for a Saint Bernard at
only 120 lbs)
