Aflatoxin found in Purina and other brands. Carcinogenic. All kibble lacks nutrition. It’s heated to such high temps, anything that was nutritious is no longer. Dogs are carnivores and yet the best dog food you can buy is only 30% protein at best. Excess carbohydrates/grains/fillers, even expensive brands, containing glyphosate. Dry dog food only came out in the 1940s. Dogs health has declined, especially in recent decades. Poor food plus so many vaxxes now=premature death. Dogs have grey muzzles now at 4-5yrs old. No one seems to notice this. Over vaxxed. 😢
