Frequently asked questions
Why do Brussels sprouts cause so much gas?
Brussels sprouts contain carbohydrates like raffinose that dogs can't break down on their own. They ferment in the gut, which produces gas (PetMD). The American Kennel Club simply calls it "lots and lots of gas".
How many Brussels sprouts can my dog eat?
To start, half a sprout to one whole sprout, depending on your dog's size (American Kennel Club). Overall, the 10% rule for treats applies. The calculator above shows the upper limit for your dog's weight.
Are Brussels sprouts bad for a dog's thyroid?
Not expected at normal amounts. In a human study, boiled or steamed Brussels sprouts didn't change thyroid levels (Galanty et al. 2024). There's no data for dogs.
