Can dogs eat blackberries? Yes. Fresh or frozen blackberries are a safe, low-calorie treat for most dogs, and they’re one of the more fiber-rich fruits you can share. Wash them, offer a handful sized to your dog, and skip blackberry jam, pie and syrup. Wild brambles are fine too, as long as you know they haven’t been sprayed.
Safe in moderation. Plain blackberries are non-toxic and need no pitting or peeling. Each berry is about 2 calories. Too many at once can cause loose stool because of the fiber, so start with a few.

Are Blackberries Good for Dogs?
They can be a smart pick when you want a fruit treat with less sugar. Based on USDA FoodData Central data, 100 grams of blackberries hold about 43 calories, 5 g of fiber and 5 g of natural sugar, along with vitamin C, vitamin K, manganese and anthocyanin antioxidants that give them their deep color. The AKC lists them as a safe fruit, and PetMD highlights their fiber and antioxidants. Your dog’s food already meets their needs, so treat the extras as a bonus.
Blackberries vs Other Berries
| Berry (100 g) | Calories | Sugar | Fiber | Verdict |
|---|---|---|---|---|
| Blackberries | 43 | ~5 g | ~5 g | Safe |
| Raspberries | 52 | ~4 g | ~6.5 g | Safe, small amounts |
| Blueberries | 57 | ~10 g | ~2.4 g | Safe |
| Strawberries | 32 | ~5 g | ~2 g | Safe |
| Grapes | Not a berry treat | Toxic, never feed | ||

How Many Blackberries Can a Dog Eat?
Fit berries into the small daily treat budget the WSAVA recommends; fiber, not calories, is usually the limit.
| Dog’s weight | Blackberries (max/day) | Approx. calories | Fiber |
|---|---|---|---|
| 10 lb (4.5 kg) | 2 to 3 | ~5 kcal | ~0.6 g |
| 25 lb (11 kg) | 5 | ~10 kcal | ~1.2 g |
| 50 lb (23 kg) | 8 to 10 | ~20 kcal | ~2.4 g |
| 75 lb (34 kg) | 12 | ~25 kcal | ~3 g |
| 100 lb (45 kg) | 15 | ~32 kcal | ~3.8 g |
Our estimates for berries of about 5 g each, from USDA values. Start at half these amounts for a dog new to berries.

How to Serve Blackberries
- Fresh: rinse and serve whole to medium and large dogs; halve for toy breeds.
- Frozen: plain frozen berries make a cooling crunch; thaw slightly for small dogs.
- Mashed: smear a few on a lick mat or mix into plain yogurt.
- Training bites: halved berries work as low-calorie rewards.
Skip: blackberry jam, pie filling, syrup, sweetened yogurt and baked goods, which add sugar and sometimes xylitol. If a label says “sugar-free”, check it against our xylitol poisoning guide.
My dog ate a lot of blackberries. Plain berries aren’t toxic, so a raid on the bowl usually means a day of gas or soft stool. Offer water and keep meals bland. Call your vet if vomiting or diarrhea lasts more than 24 hours, if there’s blood, or if your dog ate a sweetened product or one with xylitol. Dogs that browse wild bushes may also pick up thorns in the mouth or paws, or berries from sprayed hedges.

Can Dogs Eat Blackberries From the Wild?
Wild blackberries are the same fruit as store-bought ones. The risks come from the setting: brambles near roads or farms may be sprayed with pesticides, thorns can scratch eyes and gums, and unripe or moldy fruit can upset the stomach. Make sure you’re picking true blackberries, not unknown dark berries such as nightshade or pokeweed, which are toxic.
Puppies and Special Cases
- Puppies: one or two halved berries are fine once they eat solid food.
- Diabetes or weight loss: a lower-sugar fruit choice, but still ask your vet.
- Sensitive stomach: the high fiber can loosen stool; go slowly.
Can my dog eat wild blackberries on walks? The berries are fine, but avoid bushes that may be sprayed and make sure it really is a blackberry, not an unknown berry.
How many is too many? Keep it to a few as part of the treat allowance. Too many can cause loose stool.

Frequently Asked Questions
Can dogs eat blackberries frozen?
Yes. Plain frozen blackberries are a good summer treat. Halve them for small dogs.
Do blackberries contain xylitol?
Some berries contain tiny natural traces of xylitol, but the amount in a sensible serving of fresh blackberries isn’t considered a concern for dogs.
Can dogs eat blackberry leaves?
A nibble usually isn’t harmful, but leaves and thorny canes can irritate the mouth. Stick to the berries.
Can dogs eat blackberries every day?
A few a day is fine for most healthy dogs if the rest of their treats stay small. Mixing in other fruits and vegetables through the week keeps things varied and avoids too much fiber at once.
Can blackberries cause diarrhea in dogs?
Yes, if a dog eats a lot. Blackberries are high in fiber, and a sudden large serving can lead to gas or loose stool that usually settles within a day.
Are blackberries good for older dogs?
They can be. Soft, low-calorie and rich in antioxidants, blackberries are easy for senior dogs to chew. Mash them for dogs with dental problems, and check with your vet if your dog has a chronic condition.
