Hi Kenneth…I actually called ACANA and asked that same question. They assured me that the foods they sell are the exact same formulation whether produced in the U.S or Canada…that was 3 years ago….if I were you, I’d call them directly…never hurts to speak with the source…you can also go to their site or sites and do a direct comparison of the ingredient list for every single formula they sell. I’m pretty simplistic when it comes to feeding our dogs…be consistent…I believe that’s best for their digestive systems….imo though comparing ACANA to PROPLAN…if you can afford it…go ACANA.It’s an excellent food…I am a very selective person…do lots of research before making decisions, especially when it comes to those I love š
