Well they are about the same quality, MN may even be a little better. I'm not too good at knowing how much of the other ingredients are good, like the Riboflavin, biotin, copper, zinc, etc.... Bil-jac has by products which are not good and MN has none. BJ has corn in it but MN has 2 forms of corn, etc...

If I were to choose I'd say that MN may even be a little better. But thats just me & again I'm not good at knowing a lot about the bottom lower ingredients. But if Roscoe is doing good on it then that is great. Each dog is different, what may be good for one may not be good for another.
