Why do we even have dogs?

You lean back in your chain full as a tick. You simply cannot eat another bite because you suppose you’ll explode. Figuratively speaking. Then you remember there’s so many starving and hungry people in this world, you don’t want to waste your food. Suddenly, you feel a slight brush of a paw on your knee and turn to look into big, brown, hopeful eyes. Ah yes, you don’t have to feel guilty; you just give your table scraps to the family dog.
