This product killed my 4 yr old shitzu, the week before her birthday I was devastated. This product tipped her kidneys into organ failure. I gave the product for a few weeks to 3 shitzus all 3.5 + years old There were signs of addiction desperation watering eyes etc within days of receiving the product, 2 recovered and one died a horrific death. I tried to research company by calling and asking to represent product and the woman was Extremely antagonistic and confrontational my plans as a breeder were not big enough I couldn't make them enough money. Weeks later my precious movie star one of a kind girl died her symptoms never improved from taking the waffer. Not only could Vets do nothing to help her recover they were afraid of researching product to help others, fear of being dragged into lawsuit which was never intent. Stay far away from this product, far far away.
