Quick answer: Only with care. Fine in small amounts, but broccoli contains isothiocyanates that irritate a dog’s stomach when it makes up more than about 10% of the diet. The stalks are also a choking risk.
Why Broccoli Needs Care
Fine in small amounts, but broccoli contains isothiocyanates that irritate a dog’s stomach when it makes up more than about 10% of the diet. The stalks are also a choking risk.
The main thing to watch: isothiocyanates cause stomach upset in larger amounts.
How to Serve Broccoli Safely
A floret or two, steamed or raw, chopped small. Keep it an occasional garnish, not a bowlful.
What If Your Dog Already Ate Broccoli?
For most dogs, a small accidental taste is not an emergency. Watch for vomiting, diarrhea, or loss of appetite over the next 24 hours, keep fresh water available, and call your vet if symptoms appear — or sooner if your dog is very small, very young, or has existing health conditions.
