Summary
Andrew Huberman speaks with Dr. Karolina Westlund, an animal ethologist and expert in animal behavior, about the evidence-based protocols for understanding and optimizing the mental and physical health of domesticated animals. Dr. Westlund introduces the core affect space model for understanding animal emotions along two axes -- valence (pleasant vs. unpleasant) and arousal (high vs. low) -- and explains how pet owners can move their animals toward low-arousal pleasant states where they feel calm, safe, and socially engaged.
The conversation explores how different dog breeds were selectively bred from specific stages of the wolf predatory sequence -- sniffing (hounds), pointing (pointers), eyeing and stalking (border collies), chasing (greyhounds), grabbing (retrievers), and killing (terriers) -- and why understanding this heritage is essential for providing each breed with appropriate stimulation. They discuss the often misunderstood emotional needs of cats, the problems with early weaning and single housing of horses, and how humans as primates tend to project their own social behaviors (like hugging) onto animals that may not welcome such interactions.
Key Points
- Different dog breeds were selectively bred for specific stages of the wolf predatory sequence: sniffing (hounds), pointing, stalking (border collies), chasing (greyhounds), grabbing (retrievers), and killing (terriers)
- The core affect space model maps animal emotions on two axes -- valence (pleasant/unpleasant) and arousal (high/low) -- providing a framework for assessing and improving pet wellbeing
- Nose work and sniffing activities benefit virtually all dog breeds, as the sniffing component of the predatory sequence is retained across most breeds
- Horses are prey animals that forage up to 16 hours daily in the wild, and captive feeding practices that promote quick eating can lead to significant behavioral problems
- Humans as primates tend to project their own social behaviors like hugging onto pets, but many animals do not experience this as comforting
- Tactile stimulation (petting) can help animals reach calm pleasant states, but only when the animal knows and trusts the person providing it
- Understanding whether a working dog breed carries a genetic predisposition for specific predatory behaviors is essential for providing appropriate enrichment and exercise
Key Moments
Understanding what pets actually need from us
Dr. Karolina Westlund explains the science of animal behavior and what pets truly need versus what we assume they want.
"We have all sorts of ideas about what our animals want and need, but sometimes the science tells a different story."
Dogs were bred for partial predatory sequences
Selective breeding gave different breeds specific fragments of the predatory sequence, from herding to retrieving to guarding.
"We systematically intentionally bred for that like a couple hundred years ago. Then we have the ones that don't show much of the predatory sequence at all."
Displacement behaviors signal animal frustration
When motivated to proceed but unable, animals redirect activation into displacement behaviors like shaking, pacing, or chewing.
"There's motivation to move on to the next behavior, but it's not quite time yet. That activation gets an outlet."
Imprinting can cross species boundaries
Konrad Lorenz documented corvids raised from youth that started courting humans, showing how early imprinting shapes social bonds.
"Konrad Lorenz described some sort of corvid species who he also raised from young and who started courting his secretary."
Neutering removes hormonal behavior activation
Removing testes eliminates the activating effects of hormones on behavior, but dogs can still have a full quality of life.
"By removing his testes, he would not experience the activating effects of hormones. He had a great life. He was a wonderful dog."
