Can dogs eat brussels sprouts? Yes, in small amounts. Plain brussels sprouts are safe and packed with fiber and vitamins, but they're famous for causing gas, in dogs as much as in people. Steam them, cut them in halves or quarters, and stick to one or two at a time. Holiday sprouts tossed with bacon, butter or garlic are a different story.

Quick Verdict

Yes, plain and in moderation. Cooked, plain brussels sprouts are non-toxic and healthy in small portions. Cut them up so they're not a choking risk, start slow, and skip versions cooked with bacon, butter, balsamic glaze, onion or garlic.

A couple of plain, steamed sprout halves are plenty for most dogs.

What's in a Brussels Sprout?

Brussels sprouts are mini cabbages from the cruciferous family. They bring fiber, vitamin C, vitamin K and antioxidants, with very few calories. Per 100 g raw, from USDA FoodData Central:

Per 100 g (raw)Brussels sproutsCabbageBroccoli
Calories~43 kcal~25 kcal~34 kcal
Fiber~3.8 g~2.5 g~2.6 g
Vitamin C~85 mg~37 mg~89 mg
Vitamin K~177 µg~76 µg~102 µg

Approximate USDA values. One medium sprout weighs about 19 g, or roughly 8 calories.

That fiber is good for regularity in small doses. In big doses, it's where the gas comes from.

Why Sprouts Make Dogs Gassy

Brussels sprouts contain raffinose, a sugar dogs can't fully break down, and sulfur-rich compounds called glucosinolates. Gut bacteria ferment them, producing gas. A sprout or two usually means a little extra wind. A bowlful can mean bloating, belly discomfort and loose stool.

Know the difference between gas and bloat. Ordinary gas passes on its own. A swollen, tight belly, restlessness, drooling and retching that brings nothing up can be bloat (GDV), an emergency, especially in large, deep-chested breeds. Call your vet right away if you see these signs.

How to Prepare Brussels Sprouts

  • Trim the stem end and pull off any yellow or tough outer leaves.
  • Steam or boil plain for 6 to 8 minutes until tender. Cooking makes them easier to digest than raw.
  • Cut into halves for large dogs and quarters for small dogs. Whole sprouts are round and firm, and a dog that gulps can choke.
  • Cool before serving, and skip butter, oil, salt and seasoning.

Raw sprouts aren't toxic, but they're harder to chew and digest, and tend to cause more gas.

How Many Brussels Sprouts Can a Dog Eat?

Dog's weightCooked sprouts per servingFrequency
Under 15 lb½ sprout, quarteredOnce or twice a week
15 to 40 lb1 sprout, halvedOnce or twice a week
40 to 70 lb1 to 2 sproutsOnce or twice a week
Over 70 lb2 to 3 sproutsOnce or twice a week

Our estimates. Calories are low; the limit is gas and stool quality. All treats should stay under about 10% of daily calories, a guideline from WSAVA.

Holiday Sprouts to Keep Off the Plate

Brussels sprouts star on many Thanksgiving and Christmas tables, usually dressed up in ways that aren't dog-friendly:

  • Roasted with bacon or pancetta: fat and salt. See our bacon guide.
  • Garlic or shallot sprouts: both damage red blood cells, according to the ASPCA.
  • Balsamic or honey glaze: sugar and acid.
  • Parmesan or cheese sauce: fat and salt.
  • Sprouts with nuts or dried cranberries: some nuts are risky, and sweetened cranberries add sugar.

For a full list of safe and unsafe holiday foods, see what Thanksgiving food dogs can eat.

Dogs That Should Skip or Limit Them

  • Sensitive stomachs: start with a single quarter, or pick milder veggies like green beans.
  • Large, deep-chested breeds prone to bloat: keep portions small and avoid gassy foods before exercise.
  • Dogs with thyroid disease: ask your vet about cruciferous vegetables.
  • Dogs on blood thinners: vitamin K-rich foods can matter; ask your vet.

Set aside a few plain pieces before seasoning, and your dog can share the holiday safely. See our green beans and sweet potatoes guides.

Vet's Note

How many sprouts are too many? For most dogs, more than a couple at once is when gas and loose stool start. Keep them an occasional treat.

When is a bloated belly an emergency? A tight, swollen belly with retching that brings nothing up, drooling or restlessness. That can be bloat, so call your vet right away.

They're similar. Both are healthy in small amounts and both can cause gas. See our broccoli guide.
