Don't know about amazing feats but I had a dog who could count and got mad if you shot and did not kill birds. If you shot twice from the duck blind you better have a bird down or he would growl at you. Miss again and he was known to bark or nip your waders. With his reputation guest did not like to make him grumpy by missing.
His son was worse. Hunted him so long alone, by myself, he knew three shots meant three birds at absolute best, often just one or two. One day I knocked down four teal with two shots. Just freak luck at work. Hitting two teal when they buzzed the decoys is a major feat. Out he went for the first bird, goes back out for the second and returns to the blind knowing he was done. It took effort to get him do a blind retrieve on the third. He flat out refused to go for the fourth. Not to be outdone by a dog I waited until he got comfortable and shot over the decoys. Out he goes for the fourth bird on a difficult blind retrieve. Swear when he came back with the bird his look was I told you that there was no bird. You had to shoot another bird and pretend it was the same bird. I miss those dogs.
