In moderation
Why is this the verdict?
Small amounts of cooked or chopped raw broccoli are safe and provide fiber and vitamins for dogs and cats. The problem arises with large amounts: broccoli contains isothiocyanates, compounds that can irritate the gastrointestinal tract and cause gas, vomiting, or diarrhea when consumed in excess.
As a practical rule, broccoli (like other cruciferous vegetables) shouldn't exceed about 10% of a pet's daily diet. The tougher stalks should be cut into small pieces to avoid a choking hazard.
