its hard for me to ever say what i feel is BEST dog for bird hunting.i like a american long legged lab as ALL AROUND hunting dog, but to pick best, it cant be done because of the habitat,weather and hunting pressure is so different from state to state..........
but for birds from what i see here in pa the following do real good, setters/gsp/brittany spaniel are 3 that i see that really stick out.their noses and drive seem to be very good.
go to other states and the pointers are good.

all around dog covers more than just having best nose etc but thats not topic.
