shooting over dogs

Anytime I hunt by my self I shoot over my dogs. I finally got my own catch dog but he's only 6 months old right now. I've always enjoyed it because it seems if my dogs get one bayed good enough for me to ease in and get a shot it seems you can watch the bay longer. Its nice to sit back and watch em bay.
I bought a dog one time that turned out to be very gun shy and she was waiting for me at the truck about a mile away after I shot. But she was also 5yrs old. My dogs now don't seem bothered by it and they are all curs except one which is part redbone. I usually use a 45 or a 6.8spc which is similar to a 243.
