Yes. Pet Poison Helpline says "cranberries are pet safe, both raw and processed," and the AKC calls fresh and dried cranberries safe in small quantities. Too many can upset a dog's stomach. The bigger worry is the rest of the recipe, since dried fruit mixes, sauces and juices can contain raisins, grape juice, xylitol or alcohol.
If your dog ate a few plain berries, there is nothing to do. If they ate a cranberry product, grab the package and read the ingredients before deciding anything else.

Pet Poison Helpline's advice is to "check the nutrition label" for ingredients such as xylitol or grape derivatives. When you call, have the package, the amount and the time ready.
Raisins are the ingredient to take most seriously. They can cause kidney failure in dogs, and Can dogs eat grapes? explains what to do.
Call right away if your dog is choking, struggling to breathe, weak, trembling or collapses.

The small seeds inside a cranberry are edible, and PetMD suggests removing the stems. A dried cranberry and a raisin can look alike in a mixed bag, so sort them out before you share. Blueberries are a different fruit, and Can dogs eat blueberries? covers them.
How many cranberries, and how to give them
There is no cranberry chart by dog size. Pet Poison Helpline says treats outside a complete diet should make up only 5 to 10 percent of daily calories, so keep cranberries to a few at a time, and fewer for a small dog.
- Wash fresh berries and pull off any stems.
- Cut them in half for a small dog or puppy.
- Pick unsweetened dried cranberries where you can.
- Try a few the first time. The AKC suggests watching any new food for signs of stomach upset or an allergic reaction.
An AKC article on superfoods says raw cranberries can be hard for some dogs to digest, so cooked berries may sit better with some dogs.
If your dog has diabetes, sweetened dried cranberries, juice and sauce add sugar. If your dog has kidney disease or has had calcium oxalate bladder stones, ask your vet before giving cranberries, since the AKC reports a caution that large amounts may contribute to those stones.
Cranberries and urinary infections
Cranberry products are sold for bladder health. The Merck Veterinary Manual says that although cranberry extract is marketed for animals, the evidence for using it to manage bacterial urinary infections is lacking. If you think your dog has a urinary problem, see your vet, who can find the cause and treat it.
"My dog eats cranberries every Thanksgiving"
That can be true, and plain berries give most dogs no trouble. What changes from year to year is the dish. One year it is a few berries off the cutting board; the next it is a spoonful of sauce made with brandy, or a stuffing with raisins in it, which is a different exposure. Size matters too: the handful a big dog shrugs off can upset a small dog's stomach or get stuck in its throat. And some dogs simply do not handle a new food well. Treat each cranberry food by what is in it that day.

Questions about dogs and cranberries
Can dogs eat dried cranberries?
Yes, a few, if they are plain or unsweetened and the bag has no raisins or grapes mixed in. Many dried cranberries are sweetened, so keep the amount small.
Can dogs eat cranberry sauce?
Only a tiny taste of a plain sauce. The AKC says a minute amount of plain sauce is probably safe, but recipes can include lots of sugar, brandy, grapes, raisins or currants.
Can dogs drink cranberry juice?
Better not. Juice cocktail can be mostly water and sugar, and some blends contain grape juice. It is also no substitute for a vet visit if you suspect a urinary infection.
Can cranberries prevent a UTI in dogs?
There is not enough evidence to say so. Merck notes that support for cranberry extract in animal urinary infections is lacking, and ordinary cranberries have even less behind them. Your vet can diagnose and treat a UTI.
What if my dog ate cranberries with raisins?
Call your vet or a pet poison line promptly. The danger comes from the raisins, which can injure a dog's kidneys.
