Hi Oceans11-
Have you looked into any premixes? I have been using the See Spot Live Longer Dinner Mix once a week for my dogs. You just mix a meat of your choice with it and it adds the needed vitamins and minerals my dogs need. Unfortunately, it is out of production until the end of the summer. But, there are other types of premixes available that you could try. I’m also familiar with the Honest Kitchen base mixes. Other than that check out this site for some more ideas on base/pre mixes and home made diets. http://www.dogaware.com/diet/dogfoodmixes.html
Good luck, because you are right, just rotisserie chicken does not have all the nutrients your dog needs. But it is super yummy!
In the mean time, it would be beneficial to give him a multi vitamin with his chicken.
