Didn't mean to bash anybody.
Dumbest thing my ex ever did was to take the Lady to the range to condition her. She never hunted for him, did fine with me.
Pups are almost three weeks old and used to the vacuum rumbling around their pen since day 2, also tv and Uncle Phil yelling (dementia or alzheimers). The react nicely to clapping hands and will come for any loud noise once they are 6 weeks old. Loud noises mean food or treats to them.
And I had the gun shy ones too. Ex boyfriends 2 shorties were scared of birds and gun shoots. Took me two years to fix them with lots of patience and attention.
