Comparing the controllability of young hand-raised wolves and dogs
From phys.org:
During domestication, dogs most probably have been selected for increased tractability (meant as controllability or ease in handling). If so, then considerable differences should be found between domestic dogs and their closest wild relatives, wolves, in this trait. To reveal if such a difference exists, researchers at the Family Dog Project, Eötvös Loránd University assessed the development of tractability in hand-raised wolves and similarly raised, 3-to-24-week-old dogs during fetching, calling, obeying sit signal, hair brushing and walking in a muzzle.
