Having fed a dog (Virgo) both Innova and Canidae, I have to say that at least for her, I liked her coat better on Innova, but she did just fine on Canidae. I switched her because the feed mill by my grandmother's carries Canidae and it was too far for her to drive to find Innova.
But as always, it's about what works best for your dog. Aubrey has been doing great since switching from Innova to Natural Balance L&R, but Sawyer has just stuck with Innova and done wonderful on it from the get go.
Get the vet results back first before messing with her food.
