The title The Power of the Dog is rich with symbolism and layered meanings, drawing from both biblical and thematic references. It originates from a verse in the Bible, specifically Psalm 22:20, which reads: "Deliver my soul from the sword; my darling from the power of the dog." In this context, "the dog" is often interpreted as a metaphor for enemies or forces of evil, representing something vicious, relentless, and destructive. The phrase "the power of the dog" thus suggests a dangerous, predatory force that threatens to overwhelm or destroy.

In the context of Thomas Savage's 1967 novel The Power of the Dog, and its 2021 film adaptation directed by Jane Campion, the title takes on additional layers of meaning. The story explores themes of masculinity, power, cruelty, and hidden vulnerabilities, set against the backdrop of a rugged, unforgiving landscape. The "dog" in the title can be seen as a metaphor for the destructive and predatory aspects of human nature, particularly the toxic masculinity embodied by the character Phil Burbank. Phil is a domineering, manipulative, and deeply repressed rancher whose outward toughness masks his inner turmoil and vulnerability. His behavior is often likened to that of a dog—aggressive, territorial, and driven by instinct.

The "power" in the title refers not only to Phil's dominance over those around him but also to the cyclical and destructive nature of such power. It suggests how cruelty and control can perpetuate themselves, leaving lasting scars on individuals and relationships. However, the title also hints at the possibility of resistance and transformation. Just as the biblical verse calls for deliverance from the "power of the dog," the story ultimately reveals how vulnerability and compassion can challenge and dismantle such destructive forces.

In a broader sense, the title The Power of the Dog invites reflection on the duality of strength and weakness, the masks people wear to conceal their true selves, and the ways in which power can be both a source of destruction and a catalyst for change. It is a title that resonates with the novel's and film's exploration of human complexity, the tension between appearances and reality, and the enduring struggle to overcome the darker aspects of our nature.
