Did you know?
Cranberries are one of only three fruits native to North America that are commercially cultivated — alongside blueberries and Concord grapes. Native Americans used cranberries for food medicine and dye for centuries before European contact. The compound in cranberries that may prevent UTI bacteria from adhering to bladder walls — proanthocyanidins — is the subject of ongoing veterinary research. The same mechanism investigated for humans applies to dogs.
