Does your dog love you?
Animal psychologists say dogs have the emotional and cognitive intelligence of a two year old.
Though if you ask any pet owner, they will instinctively say that their four-legged companion "loves" them.
More than that, people report their dogs show "empathy" when they're upset, and can suffer from anxiety, compulsive behaviour, and depression.
But could this just be humans projecting their own feelings onto their pets?
This week we look what science has to say about dogs' emotions and delve into what our treatment of them says about the human psyche.
