A little Golden I have is being started late (3 years old) but man oh man can he retrieve. In a flash he was watching my hands,marking the fetch,just unreal. But hold on, feathers uh uh.. Wont put em in his mouth. No matter what kind of feathers. Even found a farmer that was keeping some domesticated mallards over winter. Bought a couple,and tried using the wings off them. Wont touch em not even by force. They have a slight farm smell,but if I trained with pigeons they dont carry perfume, and if you look at where some ducks are retrieved from. I've tried other types of clean feathers attatched to his dummy. Retrieving always goes well till I put feathers in the picture..Any ideas
