When Your Dog Is Literally Your World

In other studies that looked at the loyalty of dogs towards their owners, researchers have found dogs can understand verbal and physical gestures from humans, as well as their facial expressions, according to Neuroscience and Biobehavioral Reviews. According to NOVA, humans also can accurately interpret the meaning of dog barks. This ability to communicate with one another –- something not found among other species –- developed from the species reliance on one another and continues to increase their loyalty to one another.
