    Clinical Evidence

    Petz Park's strongest published canine clinical evidence is for the dental supplement ingredient Ascophyllum nodosum (Norwegian Kelp), which is the active ingredient in Plaque Control for Dogs.

    Effects of Edible Treats Containing Ascophyllum nodosum on the Oral Health of Dogs: A Double-Blind, Randomized, Placebo-Controlled Single-Center Study

    Gawor J, Jank M, Jodkowska K, Klim E, Svensson UK. Frontiers in Veterinary Science, 2018. 5:168.

    Study design: Double-blind, randomised, placebo-controlled, single-centre, 60 dogs, 90 days.

    Oral administration of edible treats containing Ascophyllum nodosum significantly reduced plaque index and calculus index compared with placebo over 90 days. Dogs in the treatment group also showed significantly lower volatile sulfur compound concentrations and better oral health status on OHI and GBI indices. The subsequent 2021 follow-up study by the same research group cited approximately 40 percent reduction in plaque deposition and 20 percent reduction in calculus formation compared with control.

    The study tested a specific commercial product (ProDen PlaqueOff) in treat form, not the Petz Park formulation. Petz Park's Plaque Control delivers the same ingredient class (Ascophyllum nodosum) at 1000mg per scoop in powder form. Subsequent research by the same authors concluded powder is the most effective delivery format for this ingredient.

    View study (DOI: 10.3389/fvets.2018.00168)

    Additional published evidence for each ingredient used in Petz Park formulations is available on the individual ingredient pages in the Ingredients Library.
