My sister got a dog and called him Chief (Captain Chief Crunchie is his long name, would you believe) in 2008 and he's been a very happy part of my extended family since then. Roman loves Chief but I don't know if Chief loves Roman in the same way ;). Unrequited doggy love, what can you do?
And Roman calls all dogs 'Shadow' after my parents dog but cats, they are just cats ;). After a little time together Roman would shout after Chief saying, "SHADOW! CHIEFY!" and it's very safe to say this boy loves his animals.
