RE: ...Speaking of rabbit hunting
Never shootaround a young dog unless they have thier nose full of game scent... They need to associate the gunshot with the game..
Even then, never shoot too CLOSE to a young dog..
Unfortunately, it only takes ONE shot to make a dog gunshy, and once they have been scared, it's darn tough to get them past it... I've read that it's possible to break a dog of guyshyness, but in 50 years of hunting, I've never seen it done...Of course, I'm not an expert at dog training, either... In my experience, the best cure to gunshyness is NOT making them gunshy in the first place..
Good luck...
