This lovely drawing of a pet and his owner is from the artist Silk Box. The text that accompanied the original tumblr post is well worth quoting in its entirety.
I was thinking about dogs, and then I was thinking about pets, and then I was thinking about beefy pets that are well-trained and sleep in an alcove under your bed, and do 50 pushups while you sit on top of them, and lick your breakfast from your fingertips and sit and lie down and spread their legs when you command it, and anyway.
