A friend of mine, (many years ago) when my kids were small, had two of those big dogs. When we were up at the lake and went over to their cabin the dogs never let our kids out of their sight. They would walk us back to our cabin sitcking close to the kids all the way. The lady who owned them spun the hair off them into "wool" and she knitted sweaters and such from it. The only down side to having them is that they slobber constantly and they do produce a LOT of slobber!!
