Why are Beagles sometimes ranked near the bottom of general obedience intelligence scales despite specializing in scent work?

Answer

Their brain is classified as specialized for olfactory work, not general obedience

The disparity highlights that classification by function is more descriptive; a Beagle’s brain is clearly classified as specialized for the highly cognitive task of scent tracking, not necessarily for complex, non-scent-related obedience commands.
