It might be effective, but the packaging is terrible.
Have tried four of these cups of polish, and each and every one has the following problem:<br /><br />1.  The top layer cover comes off easily and completely, but leaves behind a strong plastic seal.<br />2.  The super-adherent depressed plastic seal is hard to remove, and the polish stays attached to it.<br /><br />The company needs to manufacture the cover properly and add more product to the container<br /><br />Cannot tell if this thick product is any better the usual dog toothpaste, such as CET.  My dogs don't seem to like the taste nearly as much as CET.
