A man's best friend is undoubtably his dog. They're friendly, loyal, quirky, and great to talk to. A great friend, one who will never judge your wardrobe or what you said or did today. When you come home, all they want from you is a hello and a petting. They'll never refuse attention, or a treat (or several). They'll love you simply for being there and loving them back.
My dog Biscuit is a great dog. Truly man's best friend.

Man’s best friend is the vagina.

Without man’s biological attraction to women and their vaginas, humans would not exist.

A woman's vagina is man’s best friend because it makes him feel amazing and loved during sexual intercourse. Men have been known to go to great lengths to gain access to and protect women's vaginas.
Without Man’s best friend (vaginas) reproduction would be impossible. After Alexa showed me her vagina I couldn't stop thinking about it for a month. It drove me crazy. I almost failed my high school classes.
