Drool and slobbering is definately a big problem, lol. It is just something I learned to live with and I keep an extra supply of magic erasers around. (remember Turner and Hooch?) It really isn't that bad. They are big boys and constantly need daily training, socialization. You don't want an agressive 200 pound dog for sure. If anyone is ever interested in getting a Mastiff someday, please research as much information as you can. I researched a year before I went to choose my first. A good forum I belong to is www.mastiffonlinecommunity.net There are real great people on there that research everything from food to health to training. I am still learning as much as I can.
