Fear aggression results from a fearful dog resorting to its last defense - one of physical force. You don't always have to have one backed in a true, physical corner or scared to death to get the reaction. Even though there may be other avenues of action available, the dogs doesn't know of them or have the skills to see them and thinks it has no other options. Striking out of fear can become a knee-jerk reaction for them over time. Dominant dogs display this as a bossy way of keeping their things.
Fearful dogs do it as one final attempt to keep possession over the item before giving in.
As long as you are consistent in your treatment of your dominant dog and not allow her to begin to think that she is slowly vying for the role of leader, you shouldn't have much of a problem. Page last updated April 1, 1997.
