First off Joyce, dogs are omnivores not carnivores. And if hydrolyzed diets are devoid of all nutrition, as you state, how then do you explain dogs that thrive when on this diet for many years? If they weren't getting any nutrition, then they would all die as your theory claims, right? Lastly, compare the life span of a wild dog or wolf with that of a domestic dog on a hydrolyzed diet and vaccines every 3 years. Yeah, you guessed it, the domestic dog lives on average 2 times as long. Explain that, Joyce.
