I have used this product with 2 great danes who shed A LOT. Keep in mind that the pet must have its seasonal (weather change) shed but for the balance of the year it made a big difference in my pets. I stopped using it after the winter shed thinking for summer they wouldn't shed more or much but they sure did without the tabs. Referring to other review, my dogs had no negative effects.
