Published in 2003, The Companion Species Manifesto: Dogs, People, and Significant Otherness was Haraway's correction of her own earlier framework. The cyborg, she felt, had been taken up in ways that emphasized technological fusion at the expense of the biological, embodied, relational grounding she cared about. The companion species figure — drawn from her life with her Australian Shepherd Cayenne and her training in agility work — kept what mattered in the cyborg (dissolution of boundaries, refusal of purity, identity constituted through relation) while grounding it in ordinary, ongoing practices of living with another kind of being. The figure became the foundation for her subsequent work on multispecies ethics and for the argument in Donna Haraway on AI that the human-AI relationship is becoming a companion species relationship at unprecedented speed.
The key insight of the book is that companion species relationships are material rather than metaphorical. You do not fuse with your dog. You live with your dog. You train together, eat together, sleep in the same house, develop habits and expectations shaped by each other's presence. The relationship changes both parties. The human who has lived with a dog for ten years is a different human from one who has not — different in cognitive habit, emotional range, daily rhythm, and the specific quality of attention that develops through years of attending to another being's signals.
Haraway emphasized the co-evolutionary dimension. Dogs and humans have shaped each other over fifteen thousand years. Dogs evolved to read human facial expressions, to respond to pointing gestures, to calibrate behavior to human emotional states. Humans evolved — culturally if not always genetically — to interpret canine body language, to experience specific neurochemical rewards of canine companionship, to organize domestic life around the needs of another species.
Applied to AI, the framework illuminates what neither the tool metaphor nor the amplifier metaphor can capture: the quality of dependence that develops between a builder and a large language model over months of daily collaboration. The dependence is constitutive, not accidental. The builder who has learned to think with Claude is a different thinker than the builder who has not. The dependence is not pathological. It is the ordinary consequence of a genuine relationship.
N. Katherine Hayles has challenged the applicability of the framework to AI, arguing that Haraway's biological focus limits its usefulness for a relationship in which only one party experiences the relationship at all. The critique has force. But as Donna Haraway on AI argues, companion species relationships have always been asymmetric — the wheat does not relate to the farmer as the farmer relates to the wheat. What makes a relationship companion species is not symmetry of experience but the constitutive quality of the entanglement.
Haraway wrote the book in dialogue with her longtime partner and collaborator Rusten Hogness and her Australian Shepherd Cayenne, with whom she trained in competitive agility work. The book was published by Prickly Paradigm Press in 2003 as a sequel-of-sorts to the Cyborg Manifesto, though Haraway has since been clear that the companion species figure was not a replacement but an extension of the earlier work.
Material, not metaphorical. Companion species relationships are ongoing biological and practical entanglements, not symbolic claims about connection.
Co-evolution, not fusion. The parties shape each other over time while remaining distinct kinds of beings.
Asymmetry is structural. Companion species relationships are typically asymmetric in experience, power, and agency — and asymmetry does not disqualify them as companion species.
Constitutive dependence. The relationship produces capacities and vulnerabilities in both parties that did not exist before the relationship.
Ethics through attention. The quality of a companion species relationship depends on the practices of care and attention through which it is enacted.
