According to a recent study in the journal Behavioural Processes, it’s possible to predict the strength of a dog and its speed by looking at the dog’s head. The reason for this is that trade-offs between structure and physiological features constrain physical performance.
Project leader William Helton, a senior lecturer at the University of Canterbury’s Department of Psychology, explains: “In the real world, it would be hard to be both fast and efficient at running and extremely strong in combat at the same time. Nature does not allow unlimited budgets, and the trade-offs are often physical constraints.”
As a result of these physical indicators, just looking at the size, width, and basic shape of a dog’s head can then inform you about the dog’s strength and ability to run. In general, the more broad-headed a dog is, the stronger it is likely to be, according to Helton. More narrow-headed dogs tend to be speedy runners.
