A scientific journal has recently released an article about research conducted to determine whether or not your pet dog categorizes humans as by their gender. In particular, they wanted to see if dogs the use the two main cues we attend to: visual appearance and voice. To test this, dogs were sat opposite a speaker, on either side of which stood a man and a woman. The sound of a man or woman’s voice was then played through the speaker, and the scientists looked to see whether the dog looked towards the man or the woman.
