Scientists have discovered that around 80% of dogs show a consistent preference for using one front paw over the other, a trait similar to human handedness. This phenomenon, dubbed 'left pawness' or 'right pawness,' becomes apparent when dogs reach for objects, manipulate toys, or step down stairs or curbs. The findings, highlighted by dog behavior specialist Sarah Rutten in conversation with 3AW, build on recent research from Italy that confirms this lateral bias in canine motor behavior.

While paw preference might seem minor, it reflects deeper neurological patterns. In humans, handedness is linked to brain hemisphere specialization, and similar principles may apply to dogs. Observing which paw a dog uses first in specific tasks can reveal underlying cognitive tendencies and even temperament traits, according to prior studies.

The discovery opens new pathways for understanding animal behavior and welfare. For pet owners and trainers, recognizing a dog’s natural paw preference could improve training techniques and reduce stress during learning. However, researchers note that while the trend is strong, not all dogs show a clear preference—about one in five appear ambidextrous. Further study is needed to explore how this trait develops and whether it correlates with health or behavioral issues over time.
