Can Dogs Eat Brussels Sprouts? Caution — Safe but Causes Significant Gas
This food requires caution. Read the details carefully before feeding.
Plain cooked Brussels sprouts are safe for dogs but cause significant gas and digestive upset. They are high in isothiocyanates and raffinose — a sugar that ferments in the colon causing bloating and flatulence. Safe but may be unpleasant for dog and owner.

Did you know?
Brussels sprouts are named after Brussels Belgium where they have been cultivated since at least the 13th century — though some evidence suggests they were grown in ancient Rome. They were widely unpopular as a vegetable until breeding programs in the 1990s reduced the bitter glucosinolate compounds that most people found unpleasant. Modern Brussels sprouts are significantly less bitter than those served to previous generations — explaining why many adults who hated them as children find them acceptable today.

What You Need to Know
Brussels sprouts are safe in small amounts but consistently cause gas in dogs — more than most vegetables. The raffinose sugar that humans also find difficult to digest ferments in the colon producing significant gas. Cooking reduces raffinose somewhat but does not eliminate it. Small amounts of plain cooked Brussels sprouts are not harmful but the gas production makes them a less practical treat choice.
