Really depends on the dog(s)......... some need to die (yes I am serious)
People who own dnagerous/lethal pits, rotts, etc....need to understand how important it is to keep these particular animals under control. I almost lost my best friend biking over the memorial day weekend courtesy of an unrestrained pit bull/boxer mix who attacked at full speed and literally leaped into us without any warning whatsoever.
All dogs do not pose the same level of threat....... you must deal with them according to their propensity do do serious harm to you. I laugh at chihuahuas, but just as soon shoot a pit bull
