Purina Pro Plan Shredded Blends Natural Adult Dog Food

I have a Pomeranian. Her name is Izzy and she is 8 years old. I feed her Purina Pro Plan Shredded Blends Natural Adult Dog Food. When she was a puppy we fed her some sort of Eukanuba brand. The breeder that we got her from recommended it. We purchase our food from Petsmart because it is the most convenient place.
