Can Dogs Eat Cranberries? In Moderation

Why it’s fine in small amounts

Plain cranberries, fresh or cooked, are not toxic to dogs, and AKC and PetMD both say small amounts are fine. They are tart, and PetMD notes that too many can upset the stomach.

The hazards come with the packaging. Dried cranberries are often sold sweetened or mixed with other fruit, and AKC warns that some mixes include raisins, which are very toxic to dogs along with grapes. PetMD adds that trail mixes may hold raisins, chocolate or macadamia nuts. Cranberry sauce is high in sugar, and AKC notes some recipes include grapes, raisins, currants or brandy, while PetMD advises against it because of the sugar.

Cranberries are often linked to urinary health. AKC says there are not enough dog studies to confirm that they prevent urinary tract infections, and PetMD says a dog is unlikely to eat enough to benefit. AKC also notes that large amounts may contribute to calcium oxalate bladder stones, so use them sparingly and ask your vet before using supplements.

Benefits

Contain fiber, antioxidants and vitamins such as C, E and K, according to PetMD
Sometimes linked to urinary health, though dog studies are lacking

Risks

Dried mixes may contain raisins or grapes, which are toxic to dogs
Sauce, juice cocktails and sweetened dried cranberries are high in sugar and may contain alcohol or xylitol
Too many can upset the stomach
Large amounts may contribute to calcium oxalate bladder stones, according to AKC

How to serve it safely

Offer a few plain cranberries, fresh or cooked without sugar, washed and with any stems removed. Cut them in halves or quarters for small dogs. Dried cranberries should be unsweetened, free of xylitol and raisin-free, and are easy to overfeed because they are small and sugary.

Keep treats under about 10% of daily calories. Skip cranberry sauce, juice cocktails and any trail mix, and never feed raisins or grapes. If you are thinking about cranberry for urinary health, talk to your vet about proper supplements instead of human products. See also urinary tract infections.

A handful of plain cranberries may cause an upset stomach, so offer water and watch your dog.

If your dog ate a dried mix, trail mix or any dish that might have contained raisins, grapes, chocolate, macadamia nuts, alcohol or xylitol, call your vet, an emergency clinic, ASPCA Animal Poison Control at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661 (US; fees may apply) right away. Outside the US, call your local emergency vet. Do not make your dog vomit at home.

Contact your vet for diarrhea, repeated vomiting, loss of appetite, lethargy or a painful or swollen belly after any cranberry product.
