Query: What were your students doing while you were playing wack-a-rott? It sounds like nothing.

Consider that two rottweilers likely are more than a match for you and a stick, and that once one of them has latched onto you (or someone else) it might be too late to escalate to a firearm.

Given these considerations, I'd suggest that in the unlikely event the situation repeats itself, you should consider asking the students to arm themselves with anything available and to come to your assistance. The dogs were being given the impression that that they were facing only one threat. You and four students are more than a match for two rottweilers and the dogs would recognize that fact as soon as four or five people started yelling and waiving sticks at them.

By the way, my suggestion is not meant as a criticism . . . I think you handled the situation very well. I just don't believe that people can be categorized either as sheepdogs or sheep. Almost all of us have some sheepdog.
