CUVIER ON THE DOG.
"The domestic dog," says Cuvier, "is the most complete, the most singular, and the most useful conquest that man has gained in the animal world. The whole species has become our property; each individual belongs entirely to his master, acquires his disposition, knows and defends his property, and remains attached to him until death; and all this, not through constraint or necessity, but purely by the influences of gratitude and real attachment. The swiftness, the strength, the sharp scent of the dog, have rendered him a powerful ally to man against the lower tribes; and were, perhaps, necessary for the establishment of the dominion of mankind over the whole animal creation. The dog is the only animal which has followed man over the whole earth."
