Terrier's are not feared since they are small. Most people get nervous when a barking 50+ pound dog is heading there way. 20 pound and under are "awwwhhh look how cute..." you see a rot, pit, pincher etc heading your way, "....sh!t...."
I agree its their raising, I have never been around a dog that became aggressive instantly, not saying it does not or could not happen. Just my experience. My dog is part pit, she was abandoned, possibly beaten as well by her last owner. I got her from the local shelter. She becomes a nervous wreck if I raise my voice to her. I can not believe people can be so cruel to such good pets.
