Yes. Fennel bulb and seeds are safe in small amounts and may ease mild gas.

Why it’s fine

Fennel offers fiber, potassium and the aromatic compound anethole, and it has a gentle carminative reputation that extends to dogs. The crunchy bulb is low in calories, and a few seeds are harmless, though the licorice taste divides dogs sharply.

How to serve it safely

Slice a few thin pieces of raw bulb or offer a pinch of seeds as a crunchy topper. No need for much.

When to call the vet

Only large quantities would loosen stools; call your vet if diarrhea persists beyond a day.
