Most big dogs I'm not afraid of no. I am only afraid of Chows. When I was young, our neighbor invited us over to have some of their bbq. The neighbor held open his gate, I came in first, Mom and Daddy behind me. Their Chow was in the backyard, as on each occassion before when we came over and we'd play before eating. That day the Chow charged and attacked me. Our neighbor was shocked and put him in the house while Mom and Daddy carried me back home to clean me up. He came over and tried to say how sorry he was. Mom and Daddy said it was ok, I didn't need any stiches, Id be ok. I was ok, I just have some nasty scars on my thighs, arms, fingers and other places. So I am just scared of Chows. I know deep down not all attack, but at a young age when a dog you always played with attacks you, it never leaves you.
