Cranberries for Dogs: Benefits, Nutrition & Why They're in Loyal Saints
6-minute read · Reviewed against the Loyal Saints sourcing standard
Quick answer
Cranberries are a tart superfruit best known for supporting urinary tract health. They contain proanthocyanidins that may help prevent bacteria from adhering to the bladder wall, plus vitamin C and antioxidants. Loyal Saints includes real cranberries in every formula as a whole-food source of urinary and immune support.
What is cranberries, and why is it in dog food?
Cranberries are a tart, antioxidant-rich fruit with a specific and well-studied benefit: urinary tract support. Cranberries contain proanthocyanidins (PACs), compounds that may help prevent certain bacteria — particularly E. coli — from adhering to the wall of the bladder and urinary tract. This is the basis for cranberry's long-standing reputation in urinary health.
Beyond urinary support, cranberries deliver vitamin C, vitamin E, vitamin K, manganese, and a range of antioxidants. Like blueberries, they are a whole-food source of the protective compounds that support long-term health.

Do cranberries help with dog UTIs?
Cranberries contain proanthocyanidins that may help prevent certain bacteria from adhering to the urinary tract wall, which is why they are associated with urinary health.
