Can dogs eat broccoli?
A little. Broccoli is healthy in small amounts, but the florets contain isothiocyanates that can irritate the stomach in larger quantities.
Why Isothiocyanates (irritant in large amounts)
By Maya Hart
If your dog ate some
- A small amount usually causes nothing worse than a mild stomach upset.
- Offer water, skip the next treat and call your vet if vomiting or diarrhoea lasts more than a day or your pet seems unwell.
Signs to watch for
- Gas
- Vomiting
- Diarrhoea
How much, how often
Keep it below 10% of daily food — a floret or two.
Treats of any kind should stay under 10% of the day’s calories. Work out your pet’s calories
Serving it safely
- Steam or boil without seasoning
- Cut stalks small — they can cause choking
