Solid Gold Wolf King for a GSD?

Have you given your dog this food? If so, what were your opinions on it? My dogs love it, and I also put salmon oil in it as well. What were the results you got with it? I have 2 GSD (one sable (purebred), one "white"(he's not purebred, more of a mutt). Let me know! Thanks! THIS IS AN OPINION QUESTION. NO ANSWERS ARE STUPID BUT THOSE THAT ARE CONSIDERED IGNORANT WILL BE GIVEN A BAD RATING.
