Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
The Full Picture
Broccoli florets and stalks are safe for dogs in small amounts, both raw and cooked. Like cauliflower and brussels sprouts, broccoli is a cruciferous vegetable rich in fibre, vitamin C, and vitamin K. However, the florets contain isothiocyanates, which can cause mild to severe gastric irritation in some dogs if consumed in large quantities (more than 10% of daily intake). The stalks can be a choking hazard, so cut them into small pieces. Steamed broccoli without seasoning is the safest preparation. If your dog reacts badly, carrots or green beans are gentler alternatives.
What You Should Know
While broccoli is not outright toxic, there are important precautions to bear in mind before sharing it with your dog. Portion size matters, and certain preparations or varieties may be unsafe. If your dog has any existing health conditions, check with your vet first.
