If a dogless hunter listens to the guys hunting prairie grouse with several big running pointers, he'd never attempt to hunt prairie grouse without any dog at all. Well.....don't listen to them!
I really don't know how many times I've shot a double limit of sharptails between Nebraska and South Dakota, but it's been a lot. Both with and without a dog. My dog was always a lone springer spaniel named Critter. I can tell you I've shot the double limit by noon twice before I owned Critter. That's three sharptails in Nebraska and three sharptails in South Dakota, six grouse in 4-5 hours, including more than an hour of driving time between states.
It's been a long, long time since I attempted a double limit of sharptails without a dog. I bird hunted for 6 years without a dog after Critter passed and before I bought Bo, my current black Lab. But I had been hunting the Rosebud Sioux Reservation in Todd County South Dakota in the old days and once they began requiring an Indian guide for bird hunting, I never went back. So I just shot a lot of Nebraska bag limits of sharptails while attempting several combination limits without leaving Nebraska. Like sharptails & doves, sharptails & snipe, sharptails & fall turkey.
If that fact doesn't convince you that prairie grouse can be hunted without a dog, then go to Chickens & Chickens in Forums - Dogless.
