Nutritional Supplement for pets. Dr.Clauder’s Plque Ex Forte. A healthy set of teeth gives your dog a sense of well-being and enhances his quality of life. However, plaque afflicted teeth are a common problem. Dr.Clauder’s Plaque Ex is a natural dietary supplement for dogs that effectively fights the accumulation of solid plaque on teeth. The patented Lactobacillus paracasei, a type of lactic acid bacteria, prevents harmful plaque from fixing on the tooth – cell clusters form that are so heavy that they can not attach to the tooth. These clumps are naturally removed by the normal process of rubbing with the tongue. Dr.Clauder’s Plaque Ex can be given in its pure form or simply administered via the daily feed. The effectiveness of Lactobacillus paracasei is scientifically confirmed.
