Ps to OP: yes you are right to blame the neighbor/ owner, not the dog. However, i disagree that your actions caused the situation to "spiral out of control." The dog was attacking your ducks on Your property, & you attempted to protect your ducks. Most dogs will NOT bite when cornered; they will do their best to flee, or simply cower. Whether fear-aggressive, people-aggressive, livestock-aggressive, etc etc, you DID encounter an aggressive dog. That BIT you. Your actions didnt cause it to be aggressive; it already was. Please keep the blame on the owner (& by extension the aggressive dog), & not in any way on yourself. Again, you did nothing wrong in attempting to protect your ducks. Dont get me wrong; im not confrontational by nature and am very grateful i have good (rural) neighbors. But your neighbor, like her dog, has ALSO essentially attacked you first. Thats why i adamantly say to stand your ground.
