Corrected entry: Throughout the film, Chance is referred to as a 'pup' namely by Shadow, when he's actually fully grown and around the same height as Shadow.
Corrected entry: After the three pets' family drives into the pound singing a song, you can hear someone saying 'Okay, we got it.' Voice of the director ending the scene?
Correction: Actually what happens is: one of the dogs, Chance, is gloating about escaping from the pound. The cat asks, "What about me?", the dog replies "Oh yeah, Sassy the supercat.", to which Sassy laughs and replies, "You got it."
Correction: Shadow isn't saying Chance is actually a puppy. Chance is just called a "pup" because he's immature like a puppy. It's the same as referring to a young adult as "kid."
