Read it through once

The dogs sleep in the streets, all over the city. From one end of the street to the other, I suppose they will average about eight or ten to a block. Sometimes, of course, there are fifteen or twenty to a block. They do not belong to any body, and they seem to have no close personal friendships among each other. But they district the city themselves, and the dogs of each district, whether it be half a block in extent, or ten blocks, have to remain within its bounds. Woe to a dog if he crosses the line! His neighbors would snatch the balance of his hair off in a second. So it is said. But they don't look it.
