Dogs sleep well. You can read their dreams, tell exactly when they're running rabbits or warding off danger. They dream with their whole bodies. They sleep well because they have no guilt. They have no guilt because they do so little wrong.
Dogs show affection.
If only most humans could express themselves with actions, not words, and a canine's sweet and physical gestures. Dogs never talk too much. Even the female ones have a quiet dignity, at least when compared with humans. At least not that often. Dogs are never catty.
