im not sure which one is healthier but you need to go wiht one that works best with your dog that is also healthy.

I have no idea, since they are both very low quality food I have not taken the time to search which of them is better.

They are about equal, both in the lowest line of dog foods, right there with Ol’Roy, Beneful, Alpo, Gravy Train and all that junk.
Stick with Iams/Pro Plan/Purina ONE/Science Diet etc, or if you can afford it, Innova/Merrick/Chicken Soup/Natural Balance etc.
