I have always been terrified of dogs, due to the story of my late Father Z’TL running from the nazis yimach shemum ve zichrum and they let loose alsation (german shepherd) dogs on him. As my Father Z’TL was from Stanislav in Galicia and knew his city (the nazis did not know the city), he ran in to a disused warehouse and ran up 4 floors. The dogs followed up and my Father Z’TL jumped from the window to save his life, with Hashem’s help. He hurt his ankle and kept running till he found a beis medrash (it was empty). The dogs didn’t jump from the windows, of course and ran down the 4 flight of stairs. It was enough time for my Father Z’TL to flee for his life. He stayed in the beit medrash and in the evening he wanted to leave and an apparition of his Uncle Avraham Z’TL (who had sent him kaporot in 1936 to the polish army), told him it was not safe to leave and he should hide there for 3 days and then he will be safe with Hashem’s great chesed.
My frum neighbor up the road, got a dog (part collie) and we used to walk to the park nearby everyday for her exercise and ours! At first, I was so scared of the dog and would not even enter their home, never mind walking with the dog. After a while the dog got used to me and by then they got a second dog and I finally walked with the neighbor and dogs to the park every day except Shabbos and Yom Tov. When people dressed as Arabs in their long robes (hajibs) wanted to attack us in the park (totally frum neighborhood like Flatbush), the dog (one died years ago) protected us and he wanted to eat them alive! We called the police on our mobiles and the Shomrim and they caught the yemach shemam ve zicram Arabs and they were arrested! Now, I can walk with Molly (dogs name) and not have any fear!
On Pesach when she can not have the regular chometz dog food, I send up my cooked chickens from the soup for her to eat!
