I would have to vote for the Brittney. Most are much smaller than most Labs but work every bit as hard and will cover as much ground at the end of the day. I have had 4 of them with the last 2 living in the house with us full time, that includes the cars, truck, and camper. I don't know what kind of upland hunting you will be doing, but mine have hunted pheasants and quail and some woodcock, with enthusiasm and endurance beyond my own. They adapt to family living and sometimes you will swear that they can talk to you and understand what you are feeling even with out words. My current dog is around 13 or 14 years old, but I am not sure, because he came from a shelter here, and has been the best dog I have every had and it is very hard for both of us to see him having difficulties aging. Every one has their own favorites but those who advocate the Britts are hard to convince otherwise for a reason.
