Answer:
The author builds up suspense and horror through the way he describes and goes into great detail about how Cujo looks. By saying that his characteristics are blood coated on his fur, foaming at the mouth, and vicious-looking, you can visualize how the dog looks and how scary the situation is. The text is, " The dog's eyes settled on hers. They were red and rheumy. They were leaking some viscous substance. The dog seemed to be weeping gummy tears.
