I can't tell you how many times Biff has almost made someone fall off our porch because he barks at them. Those dudes selling pinestraw, Jehovah's Witnesses, kids selling magazines....there's all kinds of iratating people he scares off....I try to get him to avoid barking at the pizza man, and the girl scouts bringing cookies but hell the dog lights up every time the doorbell on The Simpsons goes off much less our own doorbell.

We recently had someone attempt to break in our house and thankfully they didn't get in because I fear for what they would have done to Biff....although for a while I think he would more than hold his own. They tried to kick in the door and Biff was sectioned off in a different part of the house but had they wanted to get anything of value they would have had to have gone through his part of the house.....now he's got free reign so if they ever came back he'd be at the front door to greet them
