Two studies have come to different conclusions about dogs and their ability to communicate. One determined that babies understand "dog speak" and another found that dogs really may not have that much to say.
A Brigham Young University study concluded that infants as young as six months can distinguish between an angry bark and friendly yap when shown pictures of dogs displaying both emotions. Researchers say the study can help understand how babies learn.
"Emotion is one of the first things babies pick up on in their social world," said BYU psychology professor Ross Flom, lead author of the study. "We chose dogs because they are highly communicative creatures both in their posture and the nature of their bark," Flom said. For more read San Francisco's Tails of City blog here.
Meanwhile, across the country, a recent study by a doctoral candidate at the University of Massachusetts found that dogs don't bark with specific messages in mind.
