I was just ordering dog food at chewy.com and according to them, Acana is opening a US plant and the formulas will be changing for that plant. I checked the Acana website and it does have a page talking about the new plant in Kentucky but nothing about changing the formulas. Danged frustrating if your dog has dietary issues! I have emailed Acana to hopefully find out from the horse's mouth as they say. Will post back if I get a response.
