Started reading about the copper that is added to dog food. There is evidence that copper is stored in the liver and can cause issues Copper Sulfate is the worst form of copper and the cheapest to use. Copper proteinate is the best form and the most expensive for a vendor to use in the dog food that they produce. I’m now looking for a kibble that uses only the copper proteinate. Some will split between the two forms to save money. So far the only food I’ve found with the proteinate is Annamaet. Fromms uses the two forms and Purina uses the sulfate. Just wondered if others have looked into this and what your thought were. Trying to find the perfect food for my danes isn’t possible but the least I can do is find one that doesn’t have the ingredients that I know are bad for them.
