In Toronto, Orijen is sold only by independent and smaller chains such as Global or Bark & Fitz. As far as I know, they do not want to sell to large chain stores.
As far as being difficult to deal with, stores may be referring to the fact that there is only one distributor for Champion Pet Foods, and that they have a minimum order that is pretty hefty for smaller stores.
I was able to tour the facility where orijen is made - it was amazing. I love it even more after seeing it made.
Rescued is my favourite breed.
