What Pets Actually Want & Need | Dr. Karolina Westlund

The episode frames pet care as an ethological problem rather than a question of human intention. Westlund describes herself as an animal ethologist, while Huberman emphasizes that common assumptions about what makes pets happy may be wrong. The practical aim is to identify species-specific drives and use evidence-based routines to support both animal welfare and the human–animal relationship.

The discussion begins with horses, which Westlund characterizes as vigilant prey animals and herd animals. Their large visual field and attention to the surrounding world differ from human perception. She argues that common captive arrangements can conflict with their evolved needs: early separation from mothers, solitary housing, and feeding practices that compress as much as sixteen hours of natural foraging into rapid meals. In her view, these mismatches can contribute to problem behavior and make captivity a poor life for many individual horses.

The conversation then turns to dogs’ smell-oriented behavior and the limits of generalizing across breeds. Westlund says she cannot establish from this discussion how much sensory capacity differs among breeds, but she can explain why interaction should reflect breeding history. A wolf’s predatory sequence includes orienting and sniffing, eyeing and stalking, chasing, grabbing, killing, dissecting, and eating. Human selection isolated parts of this sequence into breed tendencies: hounds sniff, pointers stop at pointing, border collies emphasize eyeing and controlled chasing, greyhounds chase, retrievers grab, and terriers kill.

The terrier example shows why appearance can mislead. Westies may look small and friendly, but their breeding selected them to exterminate small rodents, and an individual may track a rat in a wall for days with intense persistence. Westlund says this was intentional selection over a few hundred years. Livestock guardians retain sniffing while expressing little of the rest of the predatory sequence, and toy or lap breeds may show little interest in working-dog tasks. Her central recommendation is to understand the evolutionary work a breed was selected to perform, because that genetic history creates motivations that owners need to accommodate.

The sponsor material is separate from the interview’s substantive argument. In the conversation, Huberman uses Westlund’s breed framework to move away from simplified genetic comparisons between wolves and mastiffs. The relevant distinction is behavioral: domestication and selective breeding emphasized different stages of the predatory sequence, so owners should observe what an individual dog is motivated to do rather than assume that size or appearance tells the whole story.

Huberman describes the bulldog as a case where anatomy and historical function are intertwined. He links the short snout to bull-baiting, explains how facial structure and skin folds accompanied selection for the task, and describes Costello as having high facial pain tolerance while remaining sensitive elsewhere. He also notes the breed’s modern health problems and the effort to recover an older, less extreme line. His personal account presents Costello as highly vigilant when a threat appeared but otherwise exceptionally energy-efficient and relaxed; that is an observation about one dog, not a universal temperament claim.
