Most dogs have little problem switching to a home-cooked diet. If your dog is prone to digestive problems, you may want to make the change gradually. Add just one new ingredient at a time and wait a few days to see how your dog does before adding something else new, gradually increasing the amount of new food and decreasing the amount of the old.
If you add a lot of new ingredients at one time and your dog develops problems, it’s harder to tell what the cause might be. If your dog vomits or has diarrhea, return to his prior diet and make the change more carefully once his digestive system is back to normal. That may include feeding the new food separately from the old (at least a few hours in between meals), and feeding only one new food at a time, to see if your dog reacts to any of the new ingredients.
