The canine digestive system is best described as which type?

• A. Ruminant
• B. Hindgut fermenter
• C. Monogastric
• D. Omnivorous

Answer: (C)

The key idea is the structure of the stomach. Dogs have a single-chamber stomach, meaning they are monogastric (simple-stomached). This distinguishes them from ruminants, which have a four-compartment stomach designed for fermenting fibrous plant material, and from hindgut fermenters, which rely on microbial fermentation in the hindgut after the small intestine. While dogs do eat a mixed (omnivorous) diet, the term that best describes the digestive system’s anatomy is monogastric.
