Re: Introducing the gun.
I have always shot around the pups when hey are very young. Most young animals are not as fearful when young. Watch the pups reaction when you shoot, if it does not get frightened then you, can shoot some more and closer to the pup. If it shows any sign of fear you stop for the day and try again later from farther away. Never had a problem doing it this way, When I say about being young I am talking about under eight weeks. Being this young or not much older they seem more tolerant to the noise. Only ever had one that was gun shy and she was seven months old when I bought her, took about two to three weeks to get her over it.
