Two childhood friends find themselves forced to become enemies.

Widow Tweed: We met it seems, such a short time ago. You looked at me, needing me so. Yet from your sadness, our happiness grew. Then I found out, I need you, too. I remember how we used to play. I recall those rainy days, the fires glowed, that kept us warm. And now I find, we're both alone. Goodbye may seem forever, farewell is like the end. But in my heart's a memory, and there you'll always be.
Young Tod: Copper, you're my best friend.
Young Copper: And you're mine too, Tod.
Young Tod: And we'll always be friends forever. Won't we?
Young Copper: Yeah, forever.
Big Mama: Tod, that Copper is going to come back a hunting dog, a real killer.
Young Tod: Oh no, not my friend Copper. He won't ever change.
Big Mama: I hope you're right.
Young Tod: And we'll keep on being friends forever. Right, Big Mama?
Big Mama: Darling, forever is a long, long time, and time has a way of changing things.
Big Mama: Listen good, Tod, 'cause it's either education or elimination.
Big Mama: Oh boy, these old wings ain't what they used to be. Big Mama, you better lose a few pounds.
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.
Big Mama: Darlin, forever is a long, long time, and time has a way of changing things.
Big Mama: [to Tod] Now, if you're so foxy, and old Chief's so dumb, then why does that hound get the fox on the run? 'Cause he's got the hunter, and the hunter's got the gun. Kablaam! Elimination. Lack of education.
Adult Copper: [to Tod] I'll let you go this one time.
Young Tod: [about Chief] His ears are almost as big as yours.
Young Copper: That's not the part you gotta worry about.
Young Tod: Gosh, look at those teeth.
Young Copper: That's the part you gotta worry about!
Adult Copper: Tod... I don't want to see you get killed.
Young Tod: Oh, Big Mama, I know Copper would never track on me down. Why, Copper, he's my very best friend.
Big Mama: Ho-ho, your best friend! Now Copper's gonna do what he's been told. Supposed to chase the little fox in the old fox hole. And along comes the hunter with a buckshot load.
Boomer: [pretending to shoot a gun] K-K-Kabaam!
[Dinky pretends to get shot and falls off the tree]
Big Mama: Elimination.
Dinky: [lying on the ground] Lack of education.
Big Mama: You better believe it, Tod, yes siree.
Young Tod: You mean Copper is gonna be my enemy?
Adult Tod: We're still friends, right?
Adult Copper: Tod, those days are over. I'm a hunting dog now.
Chief: Well, well. Company has come to see the invalid.
[Amos and Copper pass by without paying attention to Chief]
Chief: How do you like that? They didn't even ask how I'm feeling.
[in trying to catch the caterpillar on an electric wire, Dinky and Boomer get zapped]
Boomer: [wheezes] Holy...
Dinky: ...smoke!
[coughs]
Young Tod: I bet you'd be good at playing Hide and Seek! Wanna try it, Copper?
Young Copper: Can I use my nose?
Young Tod: Sure. Okay, now go ahead and close your eyes and count.
[Copper turns around and covers his eyes]
Young Copper: One, two, three...
[Copper looks over his shoulder]
Young Tod: No, Copper! You can't peek!
Young Copper: Oh.
Young Tod: Now, try again.
Widow Tweed: Amos Slade, you trigger-happy lunatic! Give me that gun!
[Tweed takes the gun, then shoots Amos' radiator]
Amos Slade: My radiator! Why, you blasted female...
Widow Tweed: [pointing the gun at Amos] Hold it, right there.
Amos Slade: Watch it, that thing's loaded.
[Tweed shoots the gun in the air]
Widow Tweed: Now it ain't loaded.
[Chief has a busted leg and is whimpering loudly]
Amos Slade: Chief, get back in there before I break your other leg.
Widow Tweed: Amos Slade, that temper of yours is going to get you into a lot of trouble someday.
Amos Slade: [turns red in the face] Temper? Temper? Woman, you ain't seen my temper! If I ever catch that fox in my property again, I'll blast him, and next time I won't miss!
Adult Copper: Tod, if it's the last thing I do, I'll get you for this!
Boomer: Oh, shucks! I think I bent my b-b-b-beak.
Young Copper: If you give me a headstart I can beat you.
Adult Copper: I think I did a good job tracking down those varmints for ya.
Chief: Trackin' an' smellin' ain't enough. You gotta think nasty.
Young Tod: A worm for breakfast? Yuck!
