In life, we will have interactions that don't go our way and we will wonder "why". Most Americans will search for blame in others. A dog bites a child and instantly everyone blames the dog, but no one considers for a moment that the child could have "deserved" it. Even say that will probably get me some negative comments, but hear me out.
In life how much disrespect or rude behavior do you tolerate before you lash out. Physically or verbally? No one will scold you for standing up for yourself or no longer allowing the behavior to continue. Does the dog have that option though?
