Some People Foods Are Safe for Your Dog, Others Aren't

9. Is Broccoli Safe for Dogs?

  The answer is complicated. Broccoli is safe for dogs, within certain limitations. Broccoli does hold health benefits for dogs and contains essential nutrients, such as vitamin C, minerals, and fiber. But broccoli also contains isothiocyanates, a sulfur-based compound found in the florets which can cause gastrointestinal irritation in dogs. Isothiocyanates become toxic for a dog when the amount they consume exceeds 10 percent of their daily food requirements.

Broccoli can safely be added to a dog’s diet, provided it’s fed in small amounts.
