The Short Answer
Small amounts of plain cooked broccoli are fine. Lots of it causes serious gas and possible bowel irritation.
Why Broccoli Needs Caution
Broccoli contains isothiocyanates, which in large amounts can cause gastric irritation. The florets are worse than the stalks.
Isothiocyanates are sulfur compounds that irritate the GI lining when concentration is high. Vets say broccoli should be no more than 10% of a dog's daily food by volume.
How Much Is Actually Safe?
A few small pieces of plain cooked broccoli occasionally. Never raw stalks (choking hazard for small dogs).
Symptoms to Watch For
- Severe gas
- Bloating
- Diarrhea
- In rare cases, esophageal blockage from large stalks
When to Call the Vet
Persistent vomiting or severe bloating after eating broccoli. Bloat is a true emergency in deep-chested dogs.

The Dog Dad Take
Luna loves broccoli stalks. I steam them, cut into small pieces, and use as low-cal training treats. Florets cause too much gas in our house.
