You can't exactly ask your dog if they love you and expect a black-or-white answer. Luckily, neuroscientist and author Gregory Burns has identified ways for you to test if your dog really loves you. With a team of researchers from Emory University, Burns looked at dogs' brains with an MRI and identified parts that are associated with positive emotions. Without an MRI, Burns says you can tell your dog loves you if it: cuddles with you after meals, sleeps with you, is happy when you come home, and has love reciprocated by you.
