The Dog Knew Better

I heard this remarkable story from an eye witness:

She grew up in Strasbourg and lived on a fancy avenue on the fourth floor with her family.  The next door neighbor was a virulent anti-Semite who yelled epithets whenever he saw her father with his beard and Chassidic garb.

One seder night, Leil Shimurim, her father led his sons and sons-in-law and grandchildren downstairs and out to the street to sing Chasal Siddur Pesach.  They sang and danced and the infuriated gentile neighbor ordered his huge German Shepherd to attack her father (who was oblivious to what was happening with the neighbor).

Instead of attacking, the dog just crouched there quietly.  The women on the balcony watched this.

From then on, the neighbor did not say another word.  He saw that G-d was with this man and feared messing with him.
