Why?

Zucchini is approximately 95% water, making it extremely low in calories (about 17 calories per cup) and an excellent hydration supplement. It provides vitamins A, C, and B6, potassium, and manganese with no toxic compounds whatsoever.

Raw zucchini can be offered in slices or chunks as a crunchy treat — many dogs enjoy the mild flavor and satisfying crunch. Cooked zucchini (steamed, roasted plain) is softer and easier for older dogs. The skin, seeds, and flesh are all safe.

Wild or ornamental gourds may contain cucurbitacins — bitter compounds that can cause severe GI upset. Always offer commercially grown zucchini rather than ornamental or wild varieties. If a zucchini tastes bitter to you, do not give it to your dog.

How much is dangerous?

Not toxic. Even large amounts cause only temporary GI softness.

What are the symptoms?

ONSET:N/A — not toxic.
  • loose stools from fiber overload — not toxicity

What should I do?

⚡

No action needed. Excellent snack, especially for weight management.
