what is the meaning of life? look @ any family dog. A dog always lives a honest life, seeking companionship, staying loyal, and giving and recieving love. they had the same basic emotions as humans w/o the logical thinking BS we harbor.
A family dog will always seek to be social, stay happy by wagging his/her tail longing to hear the words "good boy!" or "good girl!" They will lovingly jump, yap and lick their human companion, and wait willingly in the house, or outside the house until they can hear his/her master's car pulling up to the driveway.
that's the meaning of life. a dog can be smarter than humans by showing us the root of life. a dog's simple 15 yr life can be very fufilling and teach us "superior" humans what it's like to live a fullfilling, happy life.
oh and ya they love to multiply as well so ..ehh..hehehe
