Verdict: In moderation
Broccoli can be given to dogs in small, infrequent amounts as a healthy treat, preferably cooked and plain. However, feeding too much, particularly the florets, can lead to gastrointestinal upset due to compounds called isothiocyanates. Always introduce new foods slowly and monitor your dog for any adverse reactions.
Isothiocyanates, found in broccoli florets, can cause gastrointestinal irritation and upset when consumed in large quantities. The stem contains lower concentrations.
