Cleansing and detoxifying our pet's liver is just as important as maintaining our own vital organ. We've identified three key nutricuticals that we've blended with USDA certified human-grade beef liver to produce a unique and healthy treat. The first ingredient is chlorella which is potent in reducing pesticides and heavy metals residing in your pet's liver. The second ingredient is Milk Thistle which attacks chemicals stored in your pet's liver from sources such as heart worm preventives, flea and tick collars or spray, shampoo, or other chemicals introduced to their system through everyday use. The third ingredient is Dandelion which is a powerful herb used for cleansing the blood which supports the liver's efforts for detoxification by up to 200%. With these three potent natural detoxifiers, you'll see why we are excited about this addition to our line of healthy treats.
