I found that because raw food is metabolized faster and there is less byproduct the dogs have less chances of defecating where it is not wanted. More food obsorption = less waste in the system and much smaller stool. Generally, raw dog food takes about 4 to 6 hours to move through your dog. Dry dog food takes a bit longer to digest and spends about 10 to 12 hours inside your dog. Several factors affect the processing and break down of the ingested food. Age of the dog, water consumption, activity level, type of food, carb to protein conversion, and other influences from the individual dog. I will defer to our more learned collegues.
