I am curious what irreversible damage she is talking about? I have weaned 6 litters and raised countless puppies on raw without feeding veggies/fruits and tons of supplements.
I glanced though her book real quick but she doesn't mention anything specific. She claims that giving a dog bones like a turkey neck can be dangerous if they don't crunch it up. I'll share some info from the book:
"A novice raw feeder doing Internet research will find many websites by those feeding nothing but chicken backs or leg quarters. Writers say that they have never had a problem with this very unbalanced diet. This may be true for their dogs, but we have seen problems, especially with young, growing dogs, and we wish to spare you the experience. The chart opposite shows the nutritional balance of such a diet. There is no iodine, and almost no vitamin D, two essential nutrients. Other minerals are short from 30-70%. 65% of the calories come from fat, as compared to about 45% in the ancestral diet."
"We find that the people feeding fresh food diets who drift the farthest from the balance of the ancestral diet are those who feed what is called "prey model". They are often feeding nothing but bony meats or chicken quarters. Because we feed only some parts of animals, other vital parts (spleen, pancreas, blood, brains, etc.) are missing. We need to make substitutions for the parts we are unable to get from the grocery store. This is done through adding fatty acids, minerals, and other nutrients. We are all for the prey model but this approach must include all the components that provide essential balance, and we just don't have some available - so we need to substitute not omit."
So her diet is muscle meat, bone meal, organ meat, fruits and veggies, krill oil, hemp oil when you feed beef, and flax oil when you feed chicken or turkey. You also need to add an egg four times a week and a can of sardines or salmon four times a week. You also have to make your own mineral mix of salt, iron, manganese, zinc, iodine, vitamin e, and taurine.
