Only thing mine takes down is a frisbee , she's kind of a wuss with loud noises (she wasn't trained as a puppy)
Thats a good looking pup. my white one doesn't have any interest in chasing anything that doesn't have feathers. Gun shyness can be trained with time and patience, I know a few really good trainers if you are interested.
It is better to die on your feet then to live on your knees.
