Answer:
That depends on the foods involved, and the nutrients each contains. If you're considering switching your dog's food, consult with your Veterinarian about how much should be fed each day. Also, remember that the switch should be made slowly, over 7 to 10 days' time, with the percentage of new food being greater each day, until the dog is eating only the new food. Making a quick change can cause stomach upset and diarrhea.
