In "Hard Dogs Don't Dance," Arturo Pérez-Reverte explores themes of loyalty and betrayal in an increasingly chaotic world. The quote, "I like who are loyal, and in these times we are not even dogs," reflects the author's disillusionment with society's diminishing values. It suggests a longing for fidelity in relationships, which seems rare in contemporary life. This sentiment evokes a stark contrast between the loyalty expected from animals and the betrayal often seen among people.

The author uses this quote to highlight a moral decline, where even the instinctual loyalty of dogs appears superior to human connections. It serves as a poignant reminder of the importance of loyalty and the profound impact its absence can have on personal relationships. Pérez-Reverte's work ultimately prompts readers to reconsider the essence of loyalty in a time when it feels increasingly threatened.
