All pets leave a lasting imprint on our lives, but your heart dog is different. Your heart dog is the dog that comes along once in a lifetime (twice if you're lucky) and grabs your heart so tightly they change the way you live your life. It's your souls true counterpart and forever a part of your emotional existence. A relationship built solely on unconditional love. You evolve together. Heart dogs shape the person you are, and who you will become. Sound dramatic? Maybe. Farfetched? Sure. But that's probably because you've never had one.
