Can dogs eat cranberries?

Yes, dogs can eat cranberries in small amounts. Like other berries such as blueberries or strawberries, fresh or unsweetened dried cranberries are harmless and can even help prevent urinary tract infections. Sugared products and cranberry juice, on the other hand, are not suitable.

What cranberries do for dogs

Cranberries provide fiber and plant compounds. More important than big health promises, though, is something else: they are tart and should only be fed in small amounts.

What to watch out for

Only feed unsweetened cranberries: sugared versions can lead to weight gain, diabetes and dental problems. Avoid cranberry products made for people (juice, sauce, jam): these often contain sugar, salt or spices that are unsuitable for dogs.

Keep the amount small: cranberries are very tart and can upset the stomach in larger quantities.

How to feed cranberries

Mix fresh cranberries in small pieces straight into your dog's food. Use unsweetened dried cranberries sparingly as a snack or training treat. A few berries a day are harmless for most dogs.

Nutritional values and amount

100 g of fresh cranberries contain about 46 kcal, 4.6 g fiber, 13.3 mg vitamin C and 85 mg potassium. Dried cranberries (unsweetened) come in at about 308 kcal per 100 g because the water content is gone. The sugar share rises to around 65 g per 100 g, so give dried versions only in very small amounts.

Guideline by body weight (fresh cranberries, per day):

• Small dogs (up to 10 kg): 2 to 3 berries
• Medium dogs (10 to 25 kg): 5 to 8 berries
• Large dogs (over 25 kg): 10 to 15 berries

For dried cranberries, halve the amount. Fresh cranberries keep in the fridge for about 4 weeks. Wash them briefly before feeding and cut them in half so your dog can chew them more easily.
