What is the scientific explanation to a dog's dislike of African-Niggers and Arabs? I originally thought that it was due to Islam, but then my boi met a Berber, Persian and Caucasian (North) and he seemed chill and friendly with them, and they happen to be muslim which essentially made my theory go to shit.

He only goes Ape-shit when he sees an African-Nigger or Arab. Like what the actual hell?
