Today I had to put down an Australian Shepherd. I was sighting in my new AR and setting up a trail camera today. As i was setting up the camera I hear what sounds like 4 dogs and what sounded like a deer bahing. I walked towards where the sound was and every once in awhile it would move so I kept tracking it. It had stopped for a couple minutes and I heard the sticks and stuff rustling and 2 dogs were growling and running at me. I raised the gun and yelled for them to stop but they didn't so i took 1 shot. It went down and the other ran away. It was about 15-20yds and a dead run at me. Bullet entered just right of its of center of his chest and exited the left side just behind is leg dead right there. Kinda got my heart racing I've never had something charge me before. Still sucks though because I like dogs. You ever had something like this happen?
