My 10.5 year old GSD/hound mix ate Acana for years. In November she became anemic, required a transfusion, which triggered underlying congestive heart failure. We have the CHF under control, but are still dealing with episodes of regenerative anemia. I’m truly hoping this is not caused by heavy metal toxicity and I will be devastated to find out that feeding her “premium” food caused the illness. Anyone else experiencing something similar?
