<P> Scud is Sid's aggressive Bull Terrier . His viciousness is first demonstrated when Sid sets a Squeeze Toy Alien on his nose and commands him to maul it mercilessly . Scud serves as an obstacle for Woody and Buzz as they try to escape Sid's house . First, as Woody tries to run off when Sid leaves the bedroom door open he encounters Scud sleeping and accidentally wakes him, forcing him and Buzz to hide . When Sid takes Buzz to the backyard to blow him up with a rocket, Woody tries to save him but Scud traps him in Sid's room . The mutant toys help Woody distract Scud so they can rescue Buzz . Scud later spots Woody and Buzz trying to escape on the moving van and pursues them, but is eluded when he runs after them into the middle of a traffic intersection and is trapped by the cars as they crash while trying to avoid him . </P> <P> Voiced by Frank Welker </P> <P> Buster is Andy's pet dachshund, whom he receives at the end of Toy Story . Buster appears in Toy Story 2 and Toy Story 3 . In Toy Story 2, he is depicted as being very energetic . Buster is considered to be nice to the toys in Andy's room and is the only one in Andy's house who knows that the toys are alive, and is fiercely loyal to Woody, obeying all commands given to him by Woody: when Wheezy is taken by Andy's mother to be sold at a yard sale, Woody is able to command Buster to carry him down to the yard sale so he can rescue Wheezy . However, he does not respond to commands from Andy whatsoever . Slinky is also able to communicate with him due to the fact they are both dogs . At the beginning of Toy Story 2, Buster finds Woody in a record of 13.5 seconds . </P> <P> In Toy Story 3, Buster is now older and looks very aged, with mixed brown and gray fur, a gray - white snout, overweight, and too old to help Woody save the other toys (in a direct parody of the rescue scene from Toy Story 2), although he remains nice and loyal to them . He tends to fall asleep as well . </P>
