If you live with a dog you just know when it’s happy or miserable, don’t you? Of course you do. Even the scientific community, now admits that dogs have emotions – even if scientists can’t directly measure what they are experiencing.

People have had a close bond with domesticated dogs for centuries. In his 1764 Dictionnaire philosophique, Voltaire observed: “It seems that nature has given the dog to man for his defence and for his pleasure. Of all the animals it is the most faithful: it is the best friend man can have.”
