According to a recent study conducted at Eotvos Lorand University in Budapest, our human ability to understand dogs probably peaks at around 10 years of age.
By age 10, children seem to develop a natural talent for decoding dog barks.
High-pitched barks with longer intervals between barks were perceived as less aggressive than faster, lower-pitched barks.
According to Pongrácz: "This relationship could have formed the basis of an evolutionary ritualization process whereby low pitched vocalizations tended to signal aggression because larger animals are more likely to win contests..high pitched vocalizations became predictors of submission or friendly intent." Study participants also associated certain barks with the emotions of despair, happiness and playfulness.
The five states were aggressiveness, despair, fear, happiness and playfulness.The researchers concluded changes in tone, pitch, and elapsed time between barks determined how study participants categorized the emotional states behind the barks.
