Is broccoli good for dogs?

Updated June 2026 — This guide has been reviewed and updated with current feeding recommendations for Irish and Northern Irish dog owners.

Yes — in small amounts, broccoli is safe and nutritious for dogs. It's packed with vitamins and fibre. But there's an important limit to know, and some parts of the broccoli plant are safer than others.

Nutritional Benefits of Broccoli for Dogs

Broccoli contains several nutrients that benefit dogs:

  • Vitamin C — supports immune function (dogs produce their own, but dietary sources are a useful boost)
  • Vitamin K — important for bone density and blood clotting
  • Fibre — supports digestive health and gut motility
  • Folate — supports cell function and growth
  • Potassium — supports heart health and muscle function

How Much Broccoli Can Dogs Eat?

Broccoli florets contain isothiocyanates — compounds that can irritate the canine digestive tract in large amounts. The guideline is:

  • Under 10% of daily caloric intake: safe as an occasional treat
  • Over 25% of daily caloric intake: can cause serious gastrointestinal distress and, in large amounts, toxicity

As a practical guide: a few florets a couple of times a week is fine for most dogs. A whole head of broccoli is too much.

Can Dogs Eat Broccoli Stalks?

The stalks are generally safer than the florets (lower in isothiocyanates), but they present a choking hazard — particularly for small dogs. If you feed the stalk, cut it into small pieces first.

Raw vs Cooked Broccoli for Dogs

Both are safe. Raw broccoli retains more nutrients but can be harder to digest. Lightly steamed broccoli (with no added salt, butter, or seasoning) is easier on the digestive system. Never give dogs broccoli cooked with garlic, onions, or oil — these are toxic to dogs.

Signs Your Dog Has Had Too Much

  • Excessive gas or flatulence
  • Loose stools or diarrhoea
  • Vomiting
  • Lethargy or reduced appetite

If you see these signs after feeding broccoli, reduce the amount or stop entirely and monitor.

Better Ways to Support Your Dog's Nutrition

While broccoli makes a nice occasional treat, the foundation of a dog's nutrition should be a complete, balanced dog food.
