Q. My dog has aggression issues towards strangers, but lately he let's people he knows pet him and while they pet him he randomly goes after their hand

A. If they are approaching him directly, this is likely triggering anxiety caused reactivity, especially if they are reaching over and above his head standing squarely toward him. Instead, they should kneel and turn sideways allowing him to smell them. They shouldn't look at him directly or do anything until he is calm. Take things at his pace. Have them offer treats with an open palm gaining his trust slowly.
