 Dogs make great listeners, and that maybe because man and man's best friend use analogous brain regions to process voices. Researchers collected almost 200,000 samples including humane-akin vocalizations, as well as environmental noises and silence. They played these clips to 22 people and 11 dogs while the subjects' brains are undergoing functional MIR scans. Humane brains tuned the most to vocal sounds. Dog brains were most sensitive to environmental noises. But they still have a lot in common. A dedicated brain area reacted strongly to the vocalizations of their own species, and that area also responded to the voices of the other species. Meanwhile, a different brain region noted emotional voice with a strong response to cheering sounds like laughter, and a weaker reaction to unhappy noises like crying and waning. The study's in the journal Current Biology. Seems that thousands years of domestication  have made our furry friends sensitive to the same vocal cues as we are. You can confide in Fido.
