Can dogs eat zucchini? Yes. Plain zucchini, raw or cooked, is one of the safest vegetables you can share. It's very low in calories, gentle on most stomachs and easy to slice into training-size coins. The skin and seeds are fine to eat. Just skip zucchini that's fried, buttered, cheesy, baked into sweet bread or cooked with onion and garlic.
Yes, plain and cut small. Zucchini is non-toxic and light enough for dogs on a diet. Serve it raw, steamed or roasted with nothing added. Introduce it slowly, since too much fiber can soften stool.

Why Zucchini Is a Good Dog Snack
Zucchini is a summer squash, about 95% water. It brings potassium, vitamin C, vitamin B6 and a little fiber, with almost no fat or sugar. Per 100 g raw, from USDA FoodData Central:
| Per 100 g (raw) | Zucchini | Cucumber | Carrot |
|---|---|---|---|
| Calories | ~17 kcal | ~15 kcal | ~41 kcal |
| Natural sugar | ~2.5 g | ~1.7 g | ~4.7 g |
| Fiber | ~1.0 g | ~0.5 g | ~2.8 g |
| Potassium | ~260 mg | ~150 mg | ~320 mg |
Approximate USDA values.
That makes zucchini a handy swap for food-motivated dogs trying to lose weight. A dozen coins have fewer calories than one small biscuit. See our weight control dog food guide for more ideas.
Raw or Cooked Zucchini?
Both are safe, so it comes down to your dog:
- Raw: crunchy and hydrating. Slice thin coins or small sticks.
- Steamed or boiled: softer for seniors, puppies and dogs with dental issues.
- Roasted: fine if roasted plain, without oil, salt or seasoning.
- Grated: mixes easily into food, and picky eaters often don't notice it.
- Frozen: frozen coins make a cool chew in summer.
The dark green skin and soft seeds are edible. Wash the skin well to remove dirt and residue.
How Much Zucchini Can a Dog Have?
| Dog's weight | Suggested amount | Rough calories |
|---|---|---|
| Under 15 lb | 2 to 3 thin coins | ~2 to 3 kcal |
| 15 to 40 lb | 4 to 6 coins | ~4 to 6 kcal |
| 40 to 70 lb | ¼ cup chopped | ~5 kcal |
| Over 70 lb | ½ cup chopped | ~10 kcal |
Our estimates; a thin coin is about 5 g. Calories are tiny, so the limit is fiber and stool quality. All treats should stay under about 10% of daily calories, a guideline from WSAVA.
Zucchini Dishes to Avoid
Zucchini bread and fried zucchini are not the same as plain zucchini. Zucchini bread is sweet and may contain raisins, walnuts, chocolate chips or xylitol. Raisins can cause kidney failure and xylitol can be life-threatening, according to the ASPCA and the FDA. Call your vet if your dog ate zucchini bread with any of those.
Also skip:
- Fried zucchini sticks: batter, oil and salt.
- Zucchini parmesan and casseroles: cheese, sauce, garlic and onion.
- Ratatouille and sautés: onion, garlic and olive oil are standard.
- Zoodles with sauce: plain spiralized zucchini is fine; pesto and tomato sauces usually contain garlic.
A Rare Warning: Bitter Squash
Very rarely, squash plants produce high levels of cucurbitacins, natural compounds that taste extremely bitter and can cause vomiting and diarrhea in people and pets. Store-bought zucchini is almost never affected, but homegrown plants occasionally are. If a zucchini tastes unusually bitter to you, throw it out rather than sharing it.
Easy Ways to Serve Zucchini
- Mix a spoonful of grated zucchini into regular food as a dog food topper.
- Bake plain coins at a low temperature until dry for a chewy, homemade dehydrated dog treat.
- Pair with plain carrots and green beans for a simple veggie mix.
- Stuff a few frozen coins in a puzzle toy on a hot day.
Zucchini vs Other Squash
| Squash | Verdict | How to serve |
|---|---|---|
| Zucchini and yellow summer squash | Safe | Raw or cooked, skin on |
| Butternut and acorn squash | Safe, cooked | Peel, seed, bake or steam plain |
| Pumpkin (plain, cooked or canned) | Safe | A spoonful, not pie filling |
| Spaghetti squash | Safe, cooked | Scoop strands, serve plain |
| Squash seeds and stems | Skip | Hard to digest; choking risk |

Is zucchini a good treat for overweight dogs? Yes. It's filling and very low in calories, so it can replace some biscuits. The main meal should still be adjusted for weight loss.
Should I peel zucchini? No need. The skin is soft and safe; just wash it well.
