Boxer:
Boxer was an enormous beast, nearly eighteen hands high, and as strong as any two ordinary horses put together. A white stripe down his nose gave him a somewhat stupid appearance, and in fact he was not of first-rate intelligence, but he was universally respected for his steadiness of character and tremendous powers of work.
Benjamin
Benjamin was the oldest animal on the farm, and the worst tempered. He seldom talked, and when he did, it was usually to make some cynical remark — for instance, he would say that God had given him a tail to keep the flies off, but that he would sooner have had no tail and no flies. Alone among the animals on the farm he never laughed. If asked why, he would say that he saw nothing to laugh at.
