Since the spring, we have our "first dog" - and the same as a puppy she had clearly get tartar. The abngepriesenen in television advertising products for tartar removal are insanely expensive and good for nothing. Our little dog had this television dental sticks swallowed up in less than 2 Mnuten - and the only thing that was less, the money was in our wallet. Then we have discovered and tried out by chance in a supermarket cattle scalp strip. SUUUUUPER - our little girl chews for days as a strip around - your tartar is completely gone - and it also increases no weight. As this bag from the grocery store was empty, we wanted the course again. Unfortunately, there was a special - so out of print. Therefore, the order via Amazon. The cattle scalp strip came quickly and the price fair. BUT (and therefore the deduction of points) other than the stink from the supermarket which unfortunately for mercy, when wet (ie, when the dog chews it). The aroma is almost so similar, like a bullwhip. We have them now mothballed in the basement and wait for the spring, when our dog bored again more in the garden. Then the outside are used .... :-)
