Wholistic Pet Organics WholeCran Intense was developed to help support your dogs urinary tract health. It features Organic Freeze-Dried Cranberries as the active ingredient. Some studies have shown that cranberries can help prevent bacteria from sticking to the urinary tract walls and make the urine more acidic which does not allow bacteria to thrive. Cranberries are also a natural source of antioxidants, flavanoids, and proanthocynidins. Wholistic Pet Organics 100% Natural Dog Supplements are Made in the USA!
