I can't defend it, but the way I imagine it is Joe being high or drunk as fukk, his dogs thing sticking out and in front of mad people and challenging people to hold it or something, nobody did and he grabbed it and called this new generation pussies, cased closed. Weirdo shyt but not bestiality or some shyt that people are making it seem like.
Him giving the dog the work is probably an exaggeration.
We are talking about a broad trying to win a case against a man, everything will be an exaggeration, even if it might be mostly true.
