Question

Dogs have short digestive systems because:

• A. It allows dogs to digest faster. This helps them run away from predators.
• B. Dogs always eat fresh, easily digestible food. Thus, they do not need long digestive systems.
• C. Dogs usually eat stale food that may be decomposing. Thus, foods must be digested quickly without risking infection.
• D. There is no specific reason for the short length. It is simply a remnant of evolution.

Answer 1

The correct option is C

Dogs usually eat stale food that may be decomposing. Thus, foods must be digested quickly without risking infection.

Dogs have short digestive systems like most carnivores. The raw meat that they consume decomposes very quickly. In addition, dogs also scavenge. By digesting their food quickly, dogs can extract most of the nutrients from their food without increasing the risk of infection by eating stale food.
