Mine’s Copper. I’m a hound dog

Young Tod: What are you smelling?
Young Copper: I'm on the trail of something.
Young Tod: Trail of… what?
Young Copper: I don't know yet.
[sniffs Tod]
Young Copper: Why it's… it's you.
[howls]
Young Tod: What'd you do that for?
Young Copper: We're supposed to do that when we find what we've been tracking.
Young Tod: I'm a fox. My name's Tod. What's your name kid?
Young Copper: Mine's Copper. I'm a hound dog.
