It took 6 miles of walking and lots of watching the dogs work, but we got into 2 large coveys and another smaller covey. Ace did wonderful work and Ruby (shown) did her very best. We harvested several Sharpies. I checked the Garmin Astro and noted the dogs ran over 30 miles on this cast! The terrain was not the easiest, either. I think both the pups will make excellent dogs!
