I fed a very similar diet for over 10 years and the old dog did great on it.
Raw chicken thigh with the bone in the mornings and a 1/2 cup of quality kibble soaked in warm water at night. Plus some salmon oil, plain yogurt, some apple cider vinegar, an egg once in awhile, liver and organ meat when I had it, etc.
The old dog did very well on this, good coat and skin, no itchy ears, very little stool, it was a good diet. Unfortunately at age 12 the old dog can't eat chicken nor raw anymore... but she did fine on this for a long time.
