What kind of whitefish does this food contain?

Answer by ChewyMar 26, 2018
The whitefish is an Ocean blend of Hake, Pollock, Cod, and Sole. It is a different mix of Ocean fish depending on the time of year and the catching seasons. All fish either are from Alaskan waters (Grand Banks), or caught off the Atlantic Ocean.

Is this food made with any type of chicken

I recently adopted a rescue dog with allergies and he was being fed a specific dog food, I figured I would just keep him on what was working for him BUT this dog food is really hard to find in stores where I live. I was going to order it through a local feed store that I regularly shop at and the expected arrival date was 7-10 days. CHEWY got it to me 2-3 days. Thanks CHEWY !!!!!

My dogs did not like this flavor at all I have one dog who would eat anything you give him but leaves this in his bowl for a while before eating.
