Scud is Sid's vicious bull terrier and horrible "toy-chewing machine", and the secondary antagonist in the first film. He has a white body with brown spots, and a red spiked collar. He has a black patch around his left eye. He immediately goes after any toys that comes into his sight, but he appears to be afraid of Sid's father, who is seen asleep on La-Z-Boy. At the end of the film, he chases after Woody and Buzz during the move until he gets trapped in a car pile-up and isn't seen from then on.
