I bought the Petzlife products (gel and spray together). I don't use it as often as I am supposed to though so I can't really attest to how well it works. It does make his breath smell nice though! No harmful ingredients. I was spraying it in Oscar's mouth and then brushing after 30 min - it's supposed to loosen up the tarter a bit and make it easier to brush. The results aren't immediate - but you should see results over time. If you do a search on here, I think there are other threads about this product as well. |
