Why I recommend feeding liver but not chicken livers
Liver is part of a balanced whole food diet for dogs. It should be fed raw and not exceed 10% of the overall diet. It could be fed once a week for instance or a little each day.
Liver is a source of Vitamins A, B, B1, B12 and K, trace elements Choline, Manganese, Molybdenum, Selenium, Cobalt and amino acid Cysteine.
Common animal livers found in Australian supermarkets are lamb liver and chicken livers. The latter are from intensively farmed chicken which have just a 30 day lifespan before they are killed. In that time, they are fed grains (often GMO grains), pumped full of growth hormones, antibiotics and are vaccinated 3 times with live virus vaccines. The liver is the organ that filters toxins and heavy metals from the body. Therefore, I do not recommend the use of chicken livers (unless you are able to source organic chicken livers).
Stick to livers from grass-fed animals where possible.
Some dogs won’t like liver and this is ok. In this instance you can feed brewers yeast instead which is abundant in B vitamins. Brewers yeast is not suitable for dogs prone to candida overgrowth (yeast infection).
