Based on the tone of your voice and your body language, your dog will do its darnedest to emulate your current state of mind. When you’re sad, they’ll look at you with big doe eyes. When your angry, the fur will rise on their backs and they’ll start barking and growling at inanimate objects. Whereas humans might not respond to your emotional upswings and downswings in a way that you’d prefer, dogs will always be there whether you’re thrilled, depressed, or anywhere in between.
