Broccoli
CautionVerdict
Small amounts OK — large amounts cause GI upset.
Toxic principle: isothiocyanate
Source: ASPCA
Verdict
Broccoli is not toxic, but the florets contain isothiocyanates — compounds that can cause significant GI irritation in dogs when eaten in large amounts. The rule of thumb: broccoli should not constitute more than 10% of a dog's daily intake. Broccoli stalks are a choking hazard. Steamed broccoli (no seasoning) is easier to digest than raw.
Symptoms to watch for
- • gas and bloating
- • diarrhea
- • vomiting (in large quantities)
- • drooling
What to do
A few small florets as an occasional treat are fine for most dogs. If your dog ate a large amount of broccoli, monitor for GI symptoms. No emergency care needed unless symptoms are severe.
