I agree. Sassy NEEDS exercise and obedience classes.

Whenever she barks at something moving outside the fence, you don't say "No" and let her continue barking. What purpose does that have? So, another BETTER option is to take an empty soda can and fill it with a couple pennies. Tape the opening shut, and toss the can towards Sassy whenever she barks. Once she stops barking and you've diverted her attention, call her name and praise and treat her. Goldens thrive on praise and human affection. However, people have the misconception that Goldens and Labs are born with the inept knowledge of Sit, Stay, Down, Come, and perfect manners. I still think re-homing Sassy is a perfectly acceptable option...
