Here's why:
* Diet: Dogs and humans have very different diets, which directly impacts the composition of their feces. Dogs eat meat, bones, and other animal products, while humans primarily eat plant-based foods.
* Digestive System: Their digestive systems also differ. Dogs have shorter intestines and a different bacterial composition in their gut, leading to variations in the breakdown of food and the resulting waste products.
* Parasites: Dogs are more susceptible to certain parasites than humans, which can be found in their feces.
* Bacteria: While both species have bacteria in their feces, the types and quantities can differ significantly.
While dog and human feces share some similarities in terms of basic components like undigested food and bacteria, their overall composition and potential health risks are distinct.
