Review (1/5): Not the original!!!
Be careful purchasing this product as there's a legal disclaimer posted for a reason!! If you've shopped around, you'll find there are some sellers asking a LOT more for this, up to $60 - those are the ones being sold in the original packaging, the hard plastic you pretty much need a chainsaw to get open. This version comes in a plastic ziploc bag with a cut-out version of the cardboard insert, and although the bottles look identical on the surface, the ingredients are not the same as the original!! The original was amazing, worked for bad breath after just one use - this version, not so much. It's missing sodium fluoride and propylene glycol, and those were apparently the magic ingredients, but I believe there's something about those ingredients that caused a problem for some pets, which is prob why they stopped selling it (and why other sellers are asking so much more $$$ for it).....unfortunately, it doesn't work without them. I wasn't paying attention, don't make the same mistake. You get what you pay for!!!
