Can dogs eat tomatoes?

Yes, dogs can eat tomatoes, but there are a few important things to bear in mind. Whilst ripe tomatoes are generally safe for dogs, unripe tomatoes and the green parts of the plant can be harmful.

Health benefits of tomatoes for dogs

Tomatoes are packed with nutrients that can be beneficial for dogs:

• Vitamin C: Helps strengthen the immune system and can reduce inflammation.
• Vitamin A: Supports healthy eyesight, skin and coat.
• Potassium: Contributes to good heart function and muscle health.
• Lycopene: A powerful antioxidant that can help combat cell damage and reduce the risk of certain diseases.

Safety of Tomatoes for Dogs

Although ripe tomatoes are safe, unripe tomatoes and the green parts of the plant (such as the leaves and stems) contain solanine, a substance that can be toxic to dogs. Solanine and the related compound tomatine belong to a class of steroidal glycoalkaloids shown in lab studies to disrupt heart cell function at higher concentrations [1]. Symptoms of solanine poisoning can include vomiting, diarrhoea, lethargy, and in severe cases, convulsions and cardiac arrhythmias.

How can you safely feed your dog tomatoes?

• Only feed ripe tomatoes: Ensure the tomatoes are fully ripe and remove all green parts.
• Portion control: Start by giving your dog only a small amount and watch for any adverse reactions.

How much tomato can your dog eat?

Ripe tomatoes can be given in moderation, depending on your dog's size:

• Small dogs: 1-2 small pieces.
• Medium-sized dogs: 2-3 small pieces.
• Large dogs: 3-4 small pieces.

Conclusion: Can dogs eat tomatoes?

Ripe tomatoes can be a healthy treat for dogs, provided they are given in moderation and the green parts are avoided. Tomatoes contain vitamins and antioxidants that can support your dog's health, but make sure your dog doesn't eat too many to prevent possible stomach upsets.
