Yes, they do! Studies have shown that dogs are able to recognize human faces, particularly if they live with families. They showed interest in the area around the eyes, which researchers perceived that the dogs do recognize faces.
While they do recognize human faces, dogs in the study were more interested in recognizing other dogs’ faces. Similar studies have shown that while dogs are able to recognize the members of their families, they have difficulty in identifying other human faces. Instead, they were able to identify other dogs with greater accuracy.
