Can dogs eat
Brussels Sprouts?
In moderation
Yes, in small amounts. Plain, cooked Brussels sprouts are safe for dogs, but they are famously gassy, so offer just a bite or two and keep seasonings out of it.
Why it’s fine in small amounts
Brussels sprouts are not toxic to dogs. They contain fiber, antioxidants and vitamins K, C, A, B1 and B6, and a plain cooked sprout makes an occasional treat for most healthy dogs.
The drawback is gas. The AKC points to isothiocyanates, which can speed food through the intestines and cause a lot of flatulence even in modest amounts. PetMD blames raffinose, a carbohydrate that dogs struggle to digest, and notes that big portions make bloating worse. Either way, the gas is unpleasant rather than dangerous, and the AKC stresses that sprouts contain no toxins, so a smelly evening is not a reason to panic.
Preparation matters. Raw sprouts are hard to digest and bitter, and PetMD says they can also cause choking or a blockage if swallowed whole. Stalks are not toxic but can upset digestion, so stick to the leaves and heads. Garlic, onion and salt, common in roasted sprouts, should never be added for your dog. Their close relative broccoli has its own cautions.
Benefits
- Provides fiber and vitamins K, C and A
- Contains antioxidants
- Also contains vitamins B1 and B6
- Not toxic, so an occasional bite is a reasonable treat
Risks
- Frequent gas and flatulence, even in small to moderate amounts
- Too many can cause stomach upset or diarrhea
- Raw sprouts are hard to digest and can cause choking or a blockage if swallowed whole
- Seasonings such as garlic, onion, salt and butter are not safe for dogs
How to serve it safely
Choose firm green sprouts, wash them, trim off most of the stem, and cut them into small pieces. Steam them plain until tender, which the AKC says takes about 5 minutes, or boil them for around 10 minutes. Let them cool completely, and leave out all herbs, spices, salt and butter.
Start with half a sprout to one sprout depending on your dog's size, and watch for gas, vomiting or diarrhea for a day. If that goes well, the AKC puts the upper limit at three sprouts per serving, offered only now and then. Small dogs should get far less. Treats should stay under about 10% of daily calories.

If your dog already ate it
If your dog ate a few plain sprouts, the usual result is gas and perhaps a loose stool. Offer water and let it pass.
See your vet if stomach upset lasts more than a few days, or sooner if your dog vomits repeatedly, has severe diarrhea, a painful belly, or is gagging on whole raw sprouts. If the sprouts were roasted with garlic or onion, call your vet, ASPCA Animal Poison Control at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661 (US; fees may apply). Do not make your dog vomit at home.
Frequently asked questions
Do Brussels sprouts give dogs gas?
Often, yes. The AKC and PetMD both warn about gas, so start with a tiny bite and cut back if your dog gets flatulent.
Can dogs eat raw Brussels sprouts?
It is better not to. The AKC says raw sprouts are hard to digest, and PetMD says they can cause choking or a blockage.
How many Brussels sprouts can a dog eat?
The AKC suggests starting with half a sprout to one, depending on size, and no more than three per serving as an occasional treat. PetMD's portion guide is smaller for little dogs, about a teaspoon or less of chopped sprout for a dog under about 20 lb (9 kg).
Are Brussels sprouts toxic to dogs?
No. The AKC says sprouts contain no toxins, so gas or mild stomach upset is not a sign of poisoning.
