Craig i start shooting around my dogs when they are pups usually start out with a 22 walking around with them in the pasture shooting if i get one that is nervous or scared of it i put them on a about a 20 ft rope and lead them and shoot and pull them to me and pet them afterwards and they usually get over it in a day or two. All my dogs will catch after i shoot but the hog hits the dirt after they are shot i use a 41 mag or 30-30 when i am hunting i never pay attention to the wind when you got 5 or 6 dogs baying the hell out of one he is not worried about what you are doin i just ease in there and watch a good bay and bust that ass when he gives me a good shot i hav seen it with just one or two dogs its a liittle harder to sneak in and get a shot
x2, Tie shy pups up close and pet.
I use a 22 cap pistol around the pups at feeding time and pet them up. I use a 22 mag pistol with solid bullets when hunting and if the hog is bayed will command the dogs to back up and then shoot and the dogs usually catch unless told otherwise.
