TWO DOGS AND A FENCE
'Nothing makes a dog madder,' said Mitchell, 'than to have another dog come outside his fence and sniff and bark at him through the cracks when he can't get out. The other dog might be an entire stranger; he might be an old chum, and he mightn't bark―only sniff―but it makes no difference to the inside dog. The inside dog generally starts it, and the outside dog only loses his temper and gets wild because the inside dog has lost his and got mad and made such a stinking fuss about nothing at all; and then the outside dog barks back and makes matters a thousand times worse, and the inside dog foams at the mouth and dashes the foam about, and goes at it like a million steel traps.
'I can't tell why the inside dog gets so wild about it in the first place, except, perhaps, because he thinks the outside dog has taken him at a disadvantage and is "poking it at him;" anyway, he gets madder the longer it lasts, and at last he gets savage enough to snap off his own tail and tear it to bits, because he can't get out and chew up that other dog; and, if he did get out, he'd kill the other dog, or try to, even if it was his own brother.
