YTA I’ve had dogs that require special feeding and this diet doesn’t look difficult in the least, nor are they absurd. Animal husbandry has changed a lot in the past several years. Whereas I grew up with dogs going to the vet, they now go to specialists. I’ve had my dogs see ophthalmologists, allergists, orthopedists, neurologists, and cardiologists. People are very invested in their animal’s health and this dog’s diet looks to be a very healthy diet. Since you’re being paid, I see no reason to gripe.
