10 Vegetables Dogs Should Eat (And 2 To Avoid)

I’ve been grooming, feeding, and creating recipes for dogs for over 20 years, and one thing I’ve learned is that vegetables can be just as powerful for dogs as meat when it comes to nutrition. Adding the right veggies to your dog’s diet can improve digestion, boost immunity, and even help maintain a shiny, healthy coat. However, not all vegetables are safe, and some can be harmful.

Key Takeaways:

• Vegetables like carrots, green beans, and sweet potatoes provide fiber, vitamins, and antioxidants for dogs.
• Low-calorie, nutrient-dense veggies can support weight management and digestion.
• Certain vegetables, such as onions and garlic, are toxic and must be avoided.
• Proper preparation (cooked or raw depending on the vegetable) enhances digestibility and nutrient absorption.
• Introduce vegetables gradually and monitor your dog for any adverse reactions.

Vegetables Dogs Should Eat

1. Carrots

Carrots are one of my favorite go-to treats for my dogs. They’re crunchy, low in calories, and high in vitamin A, which supports vision and a healthy coat. They also act as a natural teeth cleaner when given raw. I always cut them into small, bite-sized pieces to prevent choking hazards. According to veterinary nutrition research, the beta-carotene in carrots can also help boost immunity.

2. Green Beans

Green beans are packed with fiber and vitamins C and K, making them perfect for a low-calorie snack. My dogs love them steamed or lightly boiled. Never add salt or seasoning. Fun fact: green beans are often recommended in weight management diets for dogs because they add bulk without adding fat.

3. Sweet Potatoes

Sweet potatoes are a fiber and vitamin powerhouse. Rich in vitamins A, B6, and C, they help with digestion and overall gut health. I usually bake or steam them and mash them up or cut them into small chunks. Fiber-rich diets like this can help regulate stool consistency in dogs with sensitive stomachs.

4. Peas

Peas are small but mighty. They’re a good source of protein, vitamins A, B, and K, and minerals like iron. My dogs love them raw or lightly steamed. Avoid canned peas with added salt or preservatives. According to studies, peas can also help support heart health due to their antioxidant content.

5. Spinach

Spinach is rich in iron, vitamins A and C, and antioxidants, supporting immunity and skin health. I give it in moderation because high oxalate content can interfere with calcium absorption. Adding a small amount to meals occasionally can provide a nutrient boost without overdoing it.

6. Cucumbers

Cucumbers are hydrating and low-calorie, perfect for hot summer days. They contain vitamins K and C and antioxidants. I slice them into small, manageable pieces for my dogs, and they love the crunch. They’re especially good for overweight dogs as a filling, low-calorie snack.

7. Zucchini

Zucchini is low in calories and full of vitamins C and B6. It can be served raw or cooked. I usually lightly steam it for my dogs, but raw zucchini also works well as a crunchy snack. It’s excellent for dogs that need extra fiber in their diet.

8. Broccoli

Broccoli offers vitamins C and K and fiber. Cooked broccoli is easier for dogs to digest. I feed small portions because too much can cause gas. A study in canine nutrition journals shows that small amounts of broccoli can help neutralize free radicals and support overall health.

9. Brussels Sprouts

Brussels sprouts are high in vitamins A, C, and K, plus fiber. Cook them before serving to avoid digestive upset. I usually give 1–2 small halves at a time. Feeding large amounts can cause gas, so portion control is key.

10. Butternut Squash

Butternut squash is loaded with vitamins A and C and is a great source of fiber. Cooked and mashed, it’s easy for dogs to digest and mixes well into regular meals. I often blend it into their kibble to add extra nutrition without increasing calories.

Vegetables Dogs Should Avoid

1. Onions

Onions are highly toxic to dogs. They contain compounds that damage red blood cells, causing anemia. Even small amounts, raw or cooked, can be dangerous. Signs of toxicity include vomiting, lethargy, and weakness.

2. Garlic

Garlic, like onions, can cause gastrointestinal upset and red blood cell damage. Even small quantities can lead to serious health issues. Symptoms of garlic poisoning include drooling, weakness, and loss of appetite. Always keep garlic far from your dog’s diet.
