All Dog Breeds Puppy Wanted

We are a family of six, who are looking for an additional member. We are most interested in medium to large sized dogs that love the outdoors and like to be around kids, I have experience with labs, st bernad and mastifs, we have a decent sized yard and a lot of walking and running areas. My norwegian is not so good so I have b een searching a while, our kids ages range from 13-2 yrs, so I want a dog for everyone.
