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.

What You Need to Know

Plain cranberries are safe in tiny amounts but the extreme tartness makes them naturally unpalatable to most dogs. They have been used in home remedies for urinary tract health — some evidence supports cranberry's ability to prevent bacteria adhering to bladder walls. Plain unsweetened cranberry sauce or fresh cranberries in tiny amounts are not harmful. Most cranberry products for dogs contain too much sugar.
