There are very few breeds that are unsuitable for family life, as long as it is remembered that a child should never be left unsupervised with a dog, or any animal.
I suggest you make a list of traits that you would like and those you cannot see yourself coping with.
For example I couldn't live with slobber, but I have a double coated breed so there is always quite a bit of hair around the place. I can put up with one more than the other. :D
Size coat type, energy levels etc all ahve a bearing, also the job they were bred to so will have a large impact on their character traits.
