Dogs give and receive love unconditionally.
It is a nonjudgmental, completely accepting relationship. Here you are loved for who you are, not how much weight you've gained or lost, the current status of your bank account, or your popularity. Dogs do not grow up and move out. They are with you until the end of their lives. Waking with you each morning and lying nearby at night, they offer a sense of security and warmth for child and adult alike.
