If you don' t plan on doing much work with the dog and you want to hunt upland birds (mostly pheasant) get a Springer Spaniel. Make sure it is from field stock, and you won' t have to do too much to make it into a serviceable hunting dog.
It is a shame, though, that you don' t want to work with your dog very much...it is one of the great pleasures in life to fully partner with what is truly your best friend for hours at a time in the cold, quiet uplands and to take on such worthy adversaries as the chukar and hungarian partridges, or the valley quail, or the king, the ruffed grouse. If this is what you truly are looking to do, you better get an English Setter, like the 12-week-old pup below, delivering a bird to hand.
