Can Dogs Eat Zucchini? Yes

Why it’s safe

Zucchini is a safe, mild vegetable for dogs. The AKC says every part of the plant, including the leaves and flowers, is non-toxic, and PetMD calls plain zucchini safe and healthy in moderation, raw or cooked.

It is low in calories (about 20 per raw cup, according to the AKC) and offers fiber, vitamins A, C and B6, potassium and magnesium. That makes it a reasonable swap for higher-calorie treats in a dog that needs to slim down. It is not a necessity, though, because a complete dog food already covers nutrition.

Trouble comes from quantity and preparation. A big helping or a sudden switch can cause gas, bloating or diarrhea, and large raw chunks can choke a dog or block the gut, especially a small one. Zucchini fried in oil, cooked with garlic or onion, or baked into bread is a different story: the fat, salt and sugar are the problem, and some baked goods contain xylitol, which is toxic to dogs.

Benefits

Low in calories and fat, so it works as a diet-friendly treat
Fiber supports digestion and regularity
Provides vitamins A, C and B6, potassium and magnesium
Mild flavor that most dogs accept, raw or cooked

Risks

Large amounts or a sudden switch can cause gas, bloating or diarrhea
Large raw pieces can cause choking or a blockage, especially in small dogs
Added oil, butter, salt, garlic or onion makes zucchini unsafe
Zucchini bread and similar bakes add sugar and fat and may contain xylitol

How to serve it safely

Wash the zucchini, trim off the stem and chop it into bite-size pieces, or puree it. Raw is fine, and lightly steaming, boiling or baking it with nothing added makes it softer and more appealing for picky eaters or dogs that struggle to chew. A spoonful of puree spread on a lick mat is a nice slow snack. Never hand over a whole zucchini.

Portions follow size: PetMD's guide runs from about a teaspoon a day for an extra-small dog to about 3 tablespoons a day for a dog over 90 lb (41 kg). Treats should stay under about 10% of daily calories, and zucchini should not replace regular meals. If you are cooking zucchini for the family, set your dog's pieces aside before anything is seasoned.

If your dog already ate it

If your dog ate some plain zucchini, the worst outcome is usually gas or a loose stool. Offer water and watch.

Call your vet if your dog ate a very large piece or whole zucchini and is gagging, vomiting, painful or lethargic, since a blockage is possible. If the zucchini was cooked with garlic or onion, or was in a baked good that might contain xylitol, call your vet, ASPCA Animal Poison Control at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661 (US; fees may apply). Do not make your dog vomit at home.
