I don't know. My Bella has been on Fromms since I got her at 9 weeks in early December. The breeder had her on Canidea. I put coconut oil, fish oil, and apple cider vinegar in her food. She's sheds like crazy. I've pretty much given up at this point. My car, home, and body are just constantly filled with dog fur.
I will say that I *just* started her on Fromms Lamb and Lentil (grain free) after feeding her Fromms puppy, so maybe that'll make a difference. I sure hope so!
Good luck to you!
