with the kids that age, and with you wanting it to be a companion inside as well i would suggest the english setter. they are so much calmer and easier to work with. i have had shorthairs all my life, but three years back got a setter because of availablity. i will never look back. that being said there is a shorthair pup in my house, and he is nowhere the dog the setter is. i have never had a shorthair half as good as my setter. \
as far a breeders, dan penpeck (sp?) out of athens, wi has phenominal dogs and is where i picked up my setter. athens is between merrill and medford wi. a bit of a drive for you depending on where in the u.p. you are, but it will be a drive you will never regret making. i trained my dog myself, and truth be told all i had to do was guide him, as he pretty much had it in him to start with. dan breeds excellent dogs.
