My barking dog

[Big Maduro]

I'm in Columbus. The lady we got this dog from kept her crated a lot of the time it sounds like. I've tried some different training techniques, like going out the door and knocking while my son commands her to sit and "quiet" I've tried getting between her and the fence with my body like the dog whisperer. Shake cans and others. I play with her a lot. She loves fetch and would almost rather do that than eat. When someone wlks down the ally,she charges the fence and goes nuts. I appreciate all the help.
