I used Evan's book and DVD during the quarantine times last spring and went slowly, almost every day going back and reviewing video and book. Went great! To a point. I live in a suburban neighborhood with my versatile breed dog. I have a small backyard to work in, but some areas that I drive to everyday to exercise the dog and myself.
My dog will retrieve/hold/give dummies, and piles of dummies. Took him to the end of the book. But I need help with transitioning to hunting. So far this year my dog doesn't get it. We've done some upland hunting and he is back to old tricks.... finds and pickups the bird, but usually wants to come only part way back to me, drop the bird and go off hunting for another.
I have to travel some hours to get into areas where there are birds to hunt, so not easy to do, and I don't have supply of pigeons, etc.
During training I did use some frozen quail and he would stick to the program with those, in the yard.
Hoping Evan has some suggestions, or maybe he has other materials to take me that next step.
