Scud is the Phillips family's pet dog. He is a bull terrier.
- Beware of Vicious Dog: Only vicious from the toys' perspective, since he tears them up. With humans he seems relatively decent, particularly with Sid. (Then again, he did knock Hannah over like a bowling pin. Stupid dog indeed.)
- Cowboy BeBop at His Computer: In-universe. A relatively benign example but several reviews at the time referred to him as a pitbull (though one memorably said he "looked like a carpeted killer whale") though the film never refers to his breed at all. If you look at an actual pitbull vs. a bull terrier◊, it's obvious which one he's supposed to be.
- Dog Stereotype: Fits the "vicious bull terrier" stereotype.
- Dragon Their Feet: While not the last obstacle Buzz and Woody have to overcome, he's the last actual enemy they contend with, going after them even after Sid's been dealt with.
- Morality Pet: Young Sid treated him nicely and cared for him.
- Right-Hand Attack Dog: Sid's.
- Super-Persistent Predator: The only thing that will stop him from going after toys is a closed door or Sid's father.
Buster is the Davis family's pet dog. He is a dachshund.
- Big, Friendly Dog: At least he is big from toys' perspective.
- Canine Companion: Both to Andy and to Woody.
- Cool Pet: To Woody. He does tricks for Woody and helps him rescue Wheezy. And how often does a toy have a real dog as a pet?
- Good Counterpart: To Scud.
- Old Dog: In the third film. He's slower, fatter, has a gray muzzle, and is too sluggish to carry Woody around like he did as a puppy.
He is Ron's pet iguana.
- All Animals Are Dogs: Mr. Jones the iguana has a collar and acts like a dog.
- The Dragon: To Ron, and quite literally since he is an iguana. However, he abandons his status upon defecting from Ron.
- HeelFace Turn: What a life of paradise can do for a character.
- Reptiles Are Abhorrent: Played with. He is definitely the villain to the toys, but his behavior is more dog-like than reptilian, and clearly has no malicious intent to humans. It's later averted after his HeelFace Turn.
