Can Dogs Eat Cauliflower?
Short answer: Yes, plain cauliflower is safe and nontoxic for dogs, raw or cooked. Serve it plain, in bite-size pieces, and not too much at once because it can cause gas.
Why it’s okay
PetMD, in an article reviewed by a veterinarian, calls cauliflower completely safe and nontoxic for dogs. It’s low in calories, so it can be a light treat. Its fiber can cause extra gas and stomach discomfort if a dog eats a lot.
How much and how to serve it
PetMD suggests treats make up about 10% of the diet: one or two half-inch pieces for extra-small dogs (2–20 lb), up to three for small dogs (21–30 lb), five or six for medium dogs (31–50 lb), a handful for large dogs (51–90 lb) and a large handful for extra-large dogs.
Risks to watch for
- Gas and stomach discomfort from too much fiber.
- Large pieces can cause choking or a blockage. Chop it small.
- Garlic and onion seasonings are toxic. Salt and butter aren’t healthy.
What to do if your dog ate cauliflower
Most dogs only get a mild upset stomach from eating too much of a safe food. If your dog has vomiting, diarrhea or seems unwell, or if it ate a large amount, call your vet.
