From The Sayings of the Desert Fathers:
I suppose that’s true. Dogs do love their people, and they don’t judge them. They don’t generally hold grudges either…which perhaps is close to the same thing as judging. At any rate, they are very forgiving.
Dogs understand authority, too. They know who is the “top dog”, and once the hierarchy is established they tend to let it stand. One of my dogs is half again as big as our top dog, but he defers to her always.
For what it’s worth.
