We've been tossing around the idea of getting a dog. My wife is less inclined than I am. Kids are all over it (of course). I proposed a Brittany and she was more willing than she has been for most. Only question she had was how much is sheds? She's leaning to an outside only dog.
Yes, Brittanys shed quite a bit. You will have to keep the dog brushed quite often (say once a day) to keep the shedding under control. Much of their hair is quite fine too.
As far as a family dog, especially if inside with kids, you will want to pick one of the calmer puppies in the litter. That being said, a Brittany is about the most loving and easy-going people dog that you can get. Take them out for a long run everyday to burn the energy off, and they will love you and work for you and never give the kids a problem for their whole life.
