My 9 yr old dog has been diagnosed with early cardiomyopathy and hepatitis. The vet recommended the hills precription diets as the 'rolls royce' but a look at their ingredients makes me feel like the fish4dogs i already feed is better. Thoughts?

I dont like ingredients that start with non-meat....
