What Vegetables Can My Dog Eat?

Vegetables can be a nutritious, low-calorie addition to your dog’s diet, adding fibre, vitamins, and minerals while providing great enrichment. However, some vegetables are far healthier (and safer) than others, and a few should be avoided completely.

This guide explains which vegetables dogs can eat, how to prepare each one, and important safety notes to keep your dog happy and healthy.

Essential Rules Before Feeding Vegetables to Dogs

• Moderation is vital – Vegetables are healthy, but too much fibre can upset your dog’s stomach.
• Introduce slowly to monitor for digestive issues.
• Avoid seasoning – No salt, butter, oil, garlic, onions, or spices.
• Cut into dog-safe pieces to prevent choking.
• Fresh, steamed, or raw (when appropriate) is best.
