You are right that the view on raw feeding is not unanimous, but as a raw feeder I disagree that it's difficult to get the nutrients that our dogs need. I raw feed Bandit with the PMR diet and preparing it at home takes about 2 hours a month and he has never been healtheir. Also I believe that OP is getting this from a raw food company, which means they are under the same nutritional guidelines as kibble brands so I wouldn't worry much about that.
I completely agree with you to try yogurt instead of cheese though! I would also try peanut butter (although there is an ingredient called Xylitol that is toxic to dogs so check and make sure your peanut butter is safe) peanut butter is the easiest way for me to get Bandit to eat anything, and I only have to use a small amount. You could also try pumpkin (canned 100% pumpkin, not pie mix) and I've also heard of many dogs that are on a frozen raw diet where things are softer enjoy having things like raw carrots mixed in to give it a bit of crunch.
Of course if none of things work or if you just have a picky pup, I wouldn't fret too much about a small amount of cheese, just be careful with how much you are using.
