I have a one year old 170 pound Great Pyrenees Austrailian Shepard Mix. He's a real social workdog. But he is terrified of small children with anything on there faces or heads, makeup, sunglasses, hats, and especially hoods. Today he got a little more agressive and barked at a little boy with a hood. He also lunged on his leash when the little boy ran towards his moms car. Anyone got any ideas, I am a little concerned.
