Safe in small pieces, raw or cooked. Too much causes gas.
Short answer
Yes, it's perfectly fine for your dog to have small pieces of cauliflower. You can offer it raw or cooked, but make sure it's plain and cut into manageable bits to avoid a choking hazard. If your dog eats a large amount, it might experience some gas or an upset stomach. Just offer a small amount as a treat, and if you notice any unusual bloating or digestive trouble, check in with your own vet.
