Now, researchers have observed the same behavior in wolf puppies, meaning they also have the ability to understand human communication cues, according to a new study.
Researchers decided to test 13 wolf puppies born in three different litters. Their goal was to determine if wolf puppies exhibit the same behaviors as domesticated puppies, which would help them pinpoint the origin of the behaviors. Their study published Thursday in iScience, a Cell Press journal. Hansen Wheat studies the effects of domestication on behavior. She and her colleagues raised both wolf puppies and domesticated puppies from the time they were 10 days old.
But the third litter of wolf puppies ran after the ball. Two wolf puppies each retrieved the ball twice. One ran after the ball and returned it to the person three times.
