How much brussels sprouts for your dog?
Most guides say "a few pieces". Enter your dog's weight and get the actual daily ceiling, worked out from brussels sprouts's calories and the 10%-of-daily-calories treat rule vets use.
Assumes a healthy, neutered adult at a stable weight, and that this is their only treat that day. Puppies, pregnant, very active or unwell pets need different amounts — ask your vet.
Why this verdict for dogs
Brussels sprouts are safe but notorious for causing gas. Serve cooked and in small amounts.
Brussels sprouts are safe for dogs and reasonably nutritious, and they come with a consequence so reliable that it is worth planning around: this is the gassiest vegetable you can put in a dog bowl.
How much is safe?
One or two small cooked sprouts for a medium dog, chopped. That is genuinely enough. They contain isothiocyanates, which help move the gut along — and which is exactly why the gas is so pronounced. Build up slowly if you offer them at all.
What happens if a dog eats too much?
Considerable flatulence, bloating, cramping and loose stools. Uncomfortable rather than dangerous, though in deep-chested breeds anything causing significant gas and bloating deserves a little caution.
How to serve it safely
Trim, halve or chop, and steam or boil until soft with no butter, salt or oil. Never roasted in bacon fat or garlic, which is how they usually reach a table. Raw sprouts are tough and much harder to digest.

Frequently asked questions
Are they actually good for dogs?
They do contain useful fibre, vitamin K and antioxidants. Whether that is worth the gas is a household decision — green beans give you fibre without the drama.
My dog raided the Christmas sprouts — is that a problem?
Plain ones mean an uncomfortable evening. If they were cooked with bacon, butter, garlic or onion, call your vet — the seasoning is the real issue.
