Yes. The ASPCA lists the blueberry bush as non-toxic to dogs, and the AKC says dogs can eat fresh and frozen blueberries in moderation. Wash them, hand them out a few at a time, and take care with small dogs, who can choke on a whole berry.
If your dog helped themselves to plain blueberries, you usually only need to watch for a loose stool or a bit of vomiting. If it was a muffin, yogurt, jam or anything else made with blueberries, the other ingredients set the risk, so find the label.
Key takeaways
Tap a card to bring it forward.
- Plain blueberries, fresh or frozen, are non-toxic to dogs.
- Treats should stay a small slice of the day: under 10 percent of the diet (AKC) or 5 percent of calories (ASPCA).
- Whole berries can choke a small dog, so halve or mash them.
- Muffins, jam, yogurt and blueberry-flavored foods can hide xylitol, chocolate, raisins or a lot of sugar.
- A blue berry from an unknown wild plant may be something else entirely. Call before you assume.

The ASPCA's advice when you think your dog is ill or ate something poisonous is to contact your vet or its poison control center.
Call right away if your dog is gagging or choking on berries, has trouble breathing, is weak or collapses, or has vomiting, diarrhea or belly pain that is severe or keeps coming back.
How many blueberries can a dog have?
No one gives a blueberry count by dog size. The guide to use is the general treat limit. The AKC says treats should make up no more than 10 percent of your dog's daily diet, and the ASPCA's snack guide is stricter, at no more than 5 percent of daily calories. Blueberries are low in calories, so they fit that limit more easily than most people snacks.
The practical start is a few berries. The AKC suggests watching your dog closely the first time, and building from there if their stomach handles it. A small dog's share is naturally smaller than a large dog's.
How to serve blueberries
- Wash fresh berries first to rinse off dirt and any pesticide residue.
- Start with a few, and watch your dog after the first serving.
- Halve or mash them for small dogs and puppies, who are more likely to choke on a whole berry.
- Frozen berries are fine and make a cold treat on a hot day, and the AKC suggests them. A frozen berry is still a choking risk for a small dog.
- Keep them plain: no sugar, syrup, yogurt with xylitol, or chocolate.
What blueberries add to a dog's diet
The AKC describes blueberries as low in calories and a source of fiber, vitamin C, antioxidants and other plant compounds. That makes them a light treat. They are optional, though, and a dog on a complete diet does not need them.
You may see blueberries called a "superfood" for dogs. The AKC notes that the word has no standard definition. If your dog is on a special diet for a health condition, ask your vet before adding any treat.
Signs to watch for after blueberries
Most dogs show nothing at all. The ASPCA notes that eating any plant material can cause vomiting or an upset stomach, so a dog who ate a big pile of berries may have a loose stool or throw up once.
Watch more closely for:
- gagging, coughing or choking while eating, especially in a small dog
- vomiting or diarrhea that does not settle, or keeps coming back
- tiredness, weakness or belly pain
- any sign of trouble after a blueberry food with other ingredients
Any of those is a reason to call your vet.
"My dog eats blueberries off the bush every summer"
That can be a perfectly good habit. The blueberry bush is non-toxic to dogs, and plenty of dogs pick berries in the garden with no trouble. It still is not a promise for every dog, or for every berry.
Amount matters: a few berries is different from a whole bush's worth. Size matters: the AKC points out that whole berries are more of a choking risk for small dogs. Form matters: a muffin with chocolate chips brings dangers of its own. Some dogs have a more sensitive stomach than others, and an upset may show up later and go unnoticed. And a wild blue berry on a walk may belong to a different plant, which is why an unfamiliar bush deserves a call.
Muffins, dried berries and look-alikes
- Blueberry muffins, pancakes and pie: the berry is the harmless part. Check for xylitol, chocolate, raisins and a lot of fat or sugar.
- Blueberry yogurt, jam and syrup: sugar-free versions can contain xylitol, which is dangerous for dogs, and the regular ones carry a lot of sugar, according to the AKC.
- Blueberry-flavored treats and snacks: the flavor may contain little or no real blueberry. Read the label for what is actually in it.
- Dried blueberries: fine only if the label lists blueberries and nothing risky. They are more concentrated, so give fewer.
- Dried cranberries and raisins: often mixed in with dried blueberries. Raisins can cause kidney failure in dogs, so can dogs eat grapes? is the page to read if your dog ate a mix.
- Blackberries, raspberries and huckleberries: different plants. "Huckleberry" can mean several berries, so it is not a safe way to identify one.
- Blueberry powder or extract: a concentrated product that is not the same as fresh fruit. Check with your vet before using one.

Questions about dogs and blueberries
How many blueberries can you give a dog?
Start with a few, and keep all treats together under 10 percent of your dog's daily diet, per the AKC. Small dogs get fewer, and cut in half.
Are blueberries a laxative for dogs?
They are not a treatment for constipation. Blueberries contain fiber, and a large serving of any plant food can loosen the stool. If your dog is straining or has not passed stool, call your vet.
Can dogs eat frozen blueberries?
Yes. The AKC says fresh and frozen blueberries are both fine in moderation. For small dogs, thaw or halve them to cut the choking risk.
Can puppies eat blueberries?
A few, cut small or mashed, is a reasonable start. Puppies are more likely to swallow food whole, so the berry size matters more for them.
Can dogs eat dried blueberries?
Only plain ones, and fewer than fresh, since dried fruit is more concentrated and may have added sugar. Make sure they are not dried cranberries or raisins.
Are blueberries safe for cats?
The ASPCA lists the blueberry bush as non-toxic to cats as well as dogs. A few berries may still upset a cat's stomach.
