This is the infamous question passed around. Many owners, especially of our breed, are under the impression that their dog would protect them.
I however, and many others, feel that it takes a certain temperament and to an extent a certain amount of training before a dog would truly "protect" it's owner. Other dogs will either pick flight out of fight or flight in fear, or in turn WILL attack the assailant but only out of a fear aggressive response triggering them to attack to protect themselves or their security bubble. One of the biggest reasons that I opt to pick a breeder over a rescue because I as a young single female living on my own am looking for a companion AND protection animal.
A 6 year old did a very interesting video on the subject. Now of course, I would like to see this done in several different ways. Maybe a larger scale. And then actual owner's handling the dogs instead of a stranger as this could trigger a different attitude. Also, would the emotion the owner is giving off trigger a different response? Obviously this little girl isn't in TRUE fear, could a dog sense fear and respond differently? But I think in general it shows the fearful response the average pet dog would show to a true attacker.
