There you go. Here's a story, I'll try to keep it short. So we got Coco when I was just about 10 years old. We took him out and stuff but then neighborhood kids hit him with hockey sticks and he bit them. From then on mom wouldn't let us take him out. He lived inside until he was about 7 years old. Then we moved to a place without a b-y so we HAD to walk him. Mom hated this and tried to "train" him but was so nervous on the leash that he lunged at people so my sister and I had to "train" him.
We would tie his leash to a clothesline and take him to a school's field to let him blow off steam. But we would always have control by holding on to the clothesline thing. We would commence "training" after he ran for 15 minutes or so. Some dogs work best when they're tired, like LBF's dogs :) mental stimulation goes a long way. Physical stimulation was effective on my wild terrier.
After a couple years of that, Coco was very responsive to our voice while walking "cross the street", "be good", "that's a little dog", "where's Dusti"(our old tomcat)...etc.
