- Marmaduke: [Ending scene, going to sleep with Phil and Debbie again]
- [Whispering]
- Marmaduke: Wait for it... Wait for it...
- [Marmaduke farts loudly]
- Phil Winslow: Oh, Marmaduke!
- Debbie Winslow: Marmaduke!
- Phil Winslow: What did you eat?
- Carlos: Man, you got a serious problem.
- Marmaduke: [laughs] It never gets old.
- Marmaduke: [Laying down in bed with Phil and Debbie] Wait for it... Wait for it...
- [Marmaduke farts loudly]
- Phil Winslow, Debbie Winslow: Marmaduke!
- Phil Winslow: What did you eat?
- Debbie Winslow: Ew!
- Marmaduke: [Chuckles] I know it's juvenile, but it's all I've got. So there you have it. Day in the life of old Marmaduke here.
- Debbie Winslow: This is really bad.
- Marmaduke: Guys, I am sorry. T-that was - that was a little much, even for me. Bad Marmaduke. All right, enough. Lights out.
- Marmaduke: Out here, the dog park is like high school for dogs. You got you're jocks and you're cheerleaders.
- [cheerleader dog gets hit by a freebie: Freebie!]
- Marmaduke: you're drama geeks.
- [a cop pretends to shoot two dogs: Bang bang! they fall over. a dog in a hand bag: I've been in this for so long I can't feel my legs]
- Marmaduke: And you're bully's, the pedigrees.
- Bosco: Check out those ears, can you even fly with those things all what?
- [Thunder and Lighting laugh]
- Marmaduke: You think my ears are too big?
- Carlos: Those things are huge. Do friends fly free?
- Phil Winslow: Come on, I feel like we're forgetting something.
- Debbie Winslow: We have everything, but the furniture and the dog.
- Phil Winslow: Look at him, he's just sitting there.
- Debbie Winslow: I know.
- Phil Winslow: You think he'll be okay here alone?
- Debbie Winslow: I think he'll be fine. He's got food and water, and I'm having Laura from down the street look in on him.
- Phil Winslow: Right, right. I mean what's the worst that could happen? He has a party? Invite his girlfriend over?
- Marmaduke: [after they left the house] Yes and... yes!
- Marmaduke: Chupadogra?
- Chupadogra: Who are you and what are you doing here?
- Marmaduke: Please don't hurt me!
- Chupadogra: You're a big boy. Good. The small ones ain't got enough meat on their bones.
- [he snarls at Marmaduke]
- Marmaduke: Please don't hurt me! I'm sorry, I...
- [he hears the dog in a coughing fit]
- Marmaduke: Are you okay?
- Chupadogra: I'm more than all right.
- [he is still coughing]
- Chupadogra: Sorry to bother you. Hey, what's a dog like you doing out here, anyways? You're no stray.
- Marmaduke: I ran away from home.
- Chupadogra: So, you think running's the answer? Huh?
- Marmaduke: I don't even know what I'm doing anymore. I acted like a big-shot and lost all my friends, my family.
- Chupadogra: Listen, this bag of bones you're looking at used to be something special. I was the alpha dog. Left my home to go run the pack. And man, did I run it. Till they turned on me. Now I live out here alone dodging trains and dogcatchers. Rest assured, compadre, there ain't a day goes by when I don't think about waking up in a warm bed and spending the day with the folks who love me. The real me. Go home. Something tells me it ain't too late for the real you.
- Marmaduke: Thank you, Buster.
- Chupadogra: [he looks at his old bowl that reads Buster] Been a long time since anybody called me that. Thanks.
- Pedigrees: [at Marmaduke's pool] Jump, jump, jump, jump, jump!
- Golden Dog: I'm a golden dog!
- [the golden retriever jumps into the pool]
- Raisin: [deleted scene] Marmaduke. A unique synthesis of marma, the scientific name for the jumping spider family and the Duke of Marlborough, a 17th century English statesman. Am I right?
- Barbara Winslow: [flashback; Marmaduke is looking at Barbara and Brian] Marmalade.
- Brian Winslow: Duke.
- Barbara Winslow: Marmalade.
- Brian Winslow: Duke.
- Barbara Winslow: Marmalade.
- Brian Winslow: Duke!
- Barbara Winslow: Marmalade!
- Marmaduke: [back to the present] Yep, you nailed it!
- Bosco: Anyone recognize this cute little fella? The cat from the park that Marmaduke hazed?
- Carlos: Hola. I recommend the guacamole. It's dynamite!
- Bosco: Look at the tail. Turns out he lives here with Marmaduke. Or is it Marmafake?
- [the dogs look at Marmaduke]
- Marmaduke: First of all, you're not invited here, Bosco. Leave now and take Whiskers with you. We have a no cat policy.
- Carlos: Say what?
- Bosco: Oh, is that right? Then how do you explain that picture over there?
- [the dogs look at the picture of Marmaduke and Carlos]
- Bosco: I don't care how freakishly large you are, Donkey-Boy. We all know that inside, you're just a scared, little... PUP!
- Don Twombly: I'm just spitballing here but what if dogs could talk to each other?
- Phil Winslow: I don't buy it.
- Don Twombly: What if they could dance?
- Marmaduke: That's right, we're moving to the OC. O man is life gonna change. New house, new smells and the nicest bath I ever had. speaking of which, a little privacy please.
