About two months ago I got a German shepherd puppy, and now he is about 5 months old. Well, the other day I went out shooting some hand guns of mine on my own place. I didn't think much of it...I shot a couple mags out of my .45 and he sat next to me the whole time. Then I got to thinking about the noise and his ears...Will this hurt his hearing? Do any of you take your dogs out shooting? Thoughts?
