Nice look'n pup.
I've only chased ducks once....ran out for a quick jump shoot. It was high tide so I mostly intended to give the dog some exercise but we were able to sneak up on one flock of teal. I dropped one, and the dog made a nice retrieve in a deep channel. In and out in 20 minutes.
I tried to hunt opening pheasant but both places I checked out were absolutely slammed with people that we didn't hang around.
Went out another day midweek and the dog made a fantastic point on a bird but it got up and ran/flushed before I could get in for a shot. Dog locked up later on the edge of some water. I go in to flush and just hear a splash....a crippled mallard popped out of the water 10 yards away and swam away (I had lead shot so I had to let it suffer). Bumped one other rooster later that I missed.
Excited for this weekend...still not sure if I'll be working upland or ducks.
