: My name is Chance. I know, it sounds kind of funny, but most names do if you think about them for a while, maybe even yours.
: Bob was joining the family by marrying Laura. Her little girl was Hope. Hope belonged to Sassy.
Jamie was supposed to belong to me, but I didn't need anyone. I was alone. (As Jamie pranks Hope) Still, he did have a lot of really great ideas. Her oldest boy was Peter. Peter belonged to Shadow. Shadow was faithful. Shadow was loyal. Shadow was a chump. I mean, he just sat there while I had all the fun upstairs.
Chance (voiceover, referring to Shadow)
: There was more to that old boy than I gave him credit for; I was soon to discover just how much more. But even in that moment, I had to admire his faith, wherever it might lead us.
: And so began the most amazing journey of our lives.
Shadow (after Sassy has gone over the falls): I shouldn't have made her come.
Chance: But it wasn't your fault. She wanted to come.
Shadow: But it's my responsibility. I had a responsibility to Sassy. The same as I have to you, and the same as you have to Jamie.
Chance: But - we didn't ask for this job.
Shadow: We didn't have to. It's built in. Has been ever since the dawn of time, when dogs took it upon themselves to watch over man - to bark when he's in danger, to play with him when he's happy, to nuzzle him when he's lonely. That's why they call us "Man's Best Friend".
: Looking at him that night...he seemed so wise and ancient, like the first dog that ever walked the earth. And I just hoped that, one day, I could be like him.
: Shadow and Sassy had risked their lives for me. I'd never known what it was like to have friends like that. The feeling was altogether new and strange to me. I liked it.
Peter (after the other pets have returned): Come on, Shadow. (pause, nothing happens) He was old. It was too far. He was just too old.
Laura: Oh, Peter, honey...
Peter turns around and heads for the house. Then Shadow comes limping up the hill.
Peter turns and sees him.
Peter (beginning to run): Shadow!
Shadow (breaking into a run): Oh, Peter, I worried about you so.
Shadow: Peter, you're okay! Peter! I'm so happy. I thought about you all the time.
Peter: Missed you!
: I missed you, Peter, and I love you!
Chance (voiceover, directly after the above dialogue): It was Shadow's victory, really. His belief was the thing that got us through. And as I watched, I saw the years roll back from him. He was a puppy again, reunited with his best friend. And I realized, for the first time in my life, I had a family. And I realized that sacrifice, and friendship, and even love were more than just the mushy stuff.
Jamie: Come on, Chance, come inside!
