RE: Gun dog for Colorado

Are you wanting an all around dog for fur, upland and waterfowl? Then a versatile or pointing lab would suit you. But if you're just wanting an upland dog then you may also want to check out the english setter. I'm kinda of bias though. Everyone worries about their coats but a simple brush or trim the feathering and you basically have a brittany with a tail.
If you get one, get a Llewellin setter x English setter (most english setter have Llew blood in them anyways). But generally, the crosses tend more towards the english (stylish points and run big) but retain the Llew bird drive and nose.
