I was reading up a bit on fanconi and found this website that states as part of the protocol: (http://www.basenji.org/ClubDocs/fanconiprotocol2003.pdf)
2. Any good quality dry food may be fed, with the addition of at least one can per week of HIGH PROTIEN ?wet meat? mammal meat based dog food (Beef,
Lamb?etc.) to replace long-chain amino acids and phosphorus. Poultry based foods have proven far less effective in management of this disorder then mammal based meats. The only exception to this high protien diet, in this protien-losing uropathy, is documented renal failure (increasing BUN/CREATININE). In this type situation, see the ?RENAL FAILURE HYBRID PROTOCOL? section later in this instruction set
My dog doesn't have this but I feed Wellness Core and she loves it. I also feed senior wellness to my older chow who's a picky eater and just add a bit of wet sometimes and he gobbles it up π
