The Dog Mind, Measured

What we learned about how dogs actually think — from the largest cognitive dataset of its kind. This hub analyzes a research sample of 25,463 assessments drawn from that dataset — not every dog Dognition has assessed. Every dimension keeps the same color across charts, and every chart is free to download, cite, and embed.
Longitudinal findings derived from Continuous Cognitive Monitoring (CCM) — how cognition and behavior change across a dog's life — are published here as the record grows.

Four cognitive dimensions plotted against age, from puppies under one to dogs of 13 and older. Each dimension has its own trajectory — the dog mind does not simply rise and then fall.
The dog mind across a lifetime
Empathy keeps rising with age while reasoning peaks early and declines after about age eight.
Research sample of 25,463 dogs · binned by age in years, n=444 (age 12) to n=3,539 (age 3)
- Horizontal axis: Dog age
- Measured in years, binned from under 1 to 13 and older
- Vertical axis (empathy panel): Empathy — gaze score
- Measured in seconds of eye contact, 0–90
- Vertical axis (memory, reasoning, communication panels): Mean score for the age bin
- Measured in proportion of trials correct, 0–1
Sample per bin ranges from n=444 (age 12) to n=3,539 (age 3); a research sample of 25,463 dogs.

The finding: Empathy climbs steadily for a decade while reasoning peaks early and declines after age eight. An old dog reads you better than ever, even as problem-solving slows.
