My pup was starting to get more plaque and tartar build up so we decided to test out this liquid water bowl additive. I was shocked to start seeing reduced plaque on his teeth after just a weekend. In the past I was pretty inconsistent with brushing his teeth because of the fuss he would make. This has helped tremendously and his breath seems slightly less stinky since we've been using it. I have since also used a finger brush and dog toothpaste which helped whiten his teeth up even more. They say that dental chews are good, rinses are better, and brushing is best. I am good mixing all three but making this rinse a staple!
