The plant itself is not toxic, but many stevia blends are cut with xylitol or erythritol. Read the label.
Short answer
It’s probably fine as long as the stevia you used contains only the plant extract and no xylitol or erythritol. Pure stevia leaf is non‑toxic to dogs, but many commercial sweeteners are blended with sugar alcohols that are dangerous. Check the ingredient list on the product, and if you’re unsure, keep the dog away from the dish. Watch for signs of gastrointestinal upset such as vomiting or diarrhea, and call your vet if they persist.
