"My first question is : How "birdy" is your dog ?" DOC
Exactly !
The first thing you need to do is to get her interested in hunting by making it fun.
Then introduce her to softer "bangs", WHILE SHE IS DISTREACTED by her favorite Bumper/Pheasant Wing or Toy.
It's like a hunter who never feels the recoil from their gun while shooting at game.
