Blood's Possessive Heart
A Boy and His DogCharts the dog's emotional campaign to reclaim Vic: sarcasm, guilt, threats, and, finally, the unconditional wait that wins him back.

The First Sarcasm

The First Sarcasm
The Bitter Observer
Blood listens to the hours of coupling and finally breaks his pretense of sleep: he is hungry and hurt, and his master is coitusing his brains out. The dog's contempt is territorial, there is a rival in the den.
The Jealousy Begins
The fight that follows, 'You're no fucking rose garden yourself, Albert!', is the first time the partnership grinds against a third presence. Blood's hostility to Quilla June is not prejudice; it is the accurate sensing of a genuine threat.
The Prophecy of Trouble

The Prophecy of Trouble
The Warning Issued
'She's going to make trouble.' Blood states it flatly, without evidence, and is instantly right. The warning is also a bid: he is telling Vic that the girl costs more than she returns.
The Unequal Battle
Vic dismisses the prophecy, and the dog swallows his anger. The dynamic is now triangular, boy, girl, dog, and Blood knows that words will not beat a woman's body. He switches to memory and guilt.
The Debt Collector

The Debt Collector
The Burnpit Story
Blood reminds Vic of the burnpit-screamer: the glowing green thing, the attack, the near-death. The story is his trump card, the proof that he, not any woman, has bled for the boy. 'But I did it, right?'
The Guilt That Fails
Vic acknowledges the debt and goes anyway. The one moment when Blood's claim on him should be strongest is the moment Vic's new attachment proves stronger. The dog has lost, for now.
The Threat of a Better Solo

The Threat of a Better Solo
The Ultimatum
Blood threatens to find a couple of hip solos who would welcome a sharp tail-scent like him; Vic threatens to break his leg. The partnership's foundation trembles: each knows the other needs him more than he will admit.
The Unused Exit
Neither follows through. The threat itself is the measure of desperation, a dog who loves his boy so badly he would pretend to leave him. The rift is profound, but it is also a performance of pain.
The Wait That Won

The Wait That Won
The Wordless Argument
Blood is starving, wounded, weak, and present. He did not find a better solo; he did not go low mutt with a roverpak. He waited. The one word 'Hey' contains everything his jealousy, sarcasm, and threats could not say.
The Possession Completed
Vic's final choice confirms Blood's victory: the girl is killed, the dog is fed. The possessive heart is satisfied, and the satisfaction is the darkest moment in the book, because the dog's love has cost a human life.
