The loyalty, devotion and love of our four-legged canine friends is nearly always undeniable. They’re there when we need them, offering us compassion, empathy and lots of licks, the kinds of qualities and gestures that can lift our spirits and make our days a little more bearable, even under the worst of conditions. In fact, such treatment might easily lead us to believe that they’re something more than just furry, little tail-wagging companions, almost as if they’re angels in disguise.
