In fact it was altogether an odd dog, of uncertain breed, or breeds. It was large and black, but its hair was tufty, its body scrawny and clumsy, and its manner edgy, anxious, verging on the completely neurotic. Whenever it came to a halt for a moment or so, the business of starting up again often seemed to cause it trouble, as if it had difficulty in remembering where it had left each of its legs.
