Why are caecum in dogs is nonfunctional?

The caecum in dogs is considered nonfunctional because it plays a minimal role in digestion compared to herbivorous animals. In dogs, which are primarily carnivorous, the caecum is small and lacks the complex microbial fermentation processes seen in species that rely heavily on plant material. As a result, it does not significantly contribute to nutrient absorption or digestion in dogs, making it an anatomical remnant rather than a vital organ.
