Can dogs eat brussels sprouts?

Caution — gas warning

Brussels sprouts are safe for dogs but infamous for causing gas and bloating. Cooked, in small amounts only.

The full picture

Brussels sprouts are technically healthy for dogs — high in vitamins K and C, plus fibre and antioxidants. The famous side effect is also the main problem: they produce enormous amounts of gas. A small dog that eats several brussels sprouts can develop painful bloating. Always cook plain (boil, steam, or roast without oil) and offer one or two at most. Never in bacon fat, butter, or with seasoning. Skip entirely around Christmas dinners — the common pairings (bacon, chestnuts, butter) are all problematic.

Risks to watch for

  • Serious gas and bloating
  • GI upset from isothiocyanates
  • Common Christmas pairings are toxic
