Purina. They've been around forever and with no major issues. I don't understand why people fuck around with anything else. Victor's new formula is a joke. These over-priced "grain free" foods are garbage too, that will ultimately hurt your dogs. I don't know... 30yrs ago Hi Pro was just fine and no dog died from it as far as I know. Now all of the sudden it's gotta be corn free, gluten free, this free and that free. I mean wtf?! I wonder what Colby fed Pincher...
