Nothing the rep said made a difference to me.
I am not going to feed my dog by-products and PAY the high amount I pay for RC when there are other foods that do not use by-products that are cheaper in price.
I would like to hear why the rep. feels this is right. Paying MORE fo foods that contain cheap by-products? No sense to it.
I'm still trying to make sense out of HOW the change to by-products is better for my dogs. 

I can feed Hills Ideal Balance or even Science Diet kibble if I want a BIG company with lots of researchers on staff that does not use cheap by-products. There are many more companies to chose from as well that do not use by-products.
For now, I have started the transition to Fromm Chicken because the protein is the same source (chickens).
That's my little consumer opinion.

You have lost my $ RC
