It all depends on the dog food. Keeping in mind that rats don't eat meat for the most part....which is typically a prime ingredient in dog food. The more meat they get the stronger their smell usually is, high protein can cause skin issues...and certain dyes can kill them.
Usually the cheapest stuff you can find is the best stuff for rats (I would never feed it to my dogs though)
For years I used a product called Doggie Bag from Tractor Supply - has no meat all grain and bone meal based - good amount of vitamins and protein at 16% so was perfect for rats. I was buying 50lbs for $10
Basically you need to read the bag. Even better is to combine several products to make your own well balanced feed.
Hope this helps.
