While researching this year’s dry dog food review (which starts on the facing page), I was struck by the overwhelming prevalence of two big trends in marketing and formulation. I’m not sure any pet food company is immune from these tactics – and I’m not yet convinced they will prove a benefit to dogs or dog owners. The first tactic is the “No!” approach. You know, “No Corn, wheat, or soy!” How tame those claims seem now. I’ve seen dog food bags and pet food company literature that proudly proclaims products free of beef, dairy products, eggs, pork, potatoes, and yeast.
