Can Dogs Eat tomatoes?

The short answer is: yes, dogs can eat tomatoes in moderation. It's important for dog owners to understand what foods are safe for their dogs, as some can be toxic or harmful in large amounts. Tomatoes, when properly prepared and fed in moderation, can provide a healthy source of vitamins, minerals, and antioxidants for our canine friends.

Nutritional Benefits of Tomatoes for Dogs

Vitamins and Minerals

Tomatoes are a nutrient-rich fruit and can provide the following vitamins and minerals for your dog:

  • Vitamin A
  • Vitamin C
  • Potassium
  • Folate
  • Lycopene


Tomatoes are also a good source of antioxidants, which can help protect your dog's body from damage caused by free radicals. Including antioxidant-rich foods in your dog's diet can contribute to their overall health and well-being.

Potential Risks and Toxicity of Tomatoes for Dogs

Nightshade Family

Tomatoes belong to the nightshade family of plants, which also includes potatoes, eggplants, and peppers. Some plants in this family can be toxic to dogs due to the presence of certain compounds.

Solanine and Tomatine

Solanine and tomatine are two toxic compounds found in some nightshade plants. These compounds can be harmful to dogs, causing symptoms like gastrointestinal upset, weakness, and even more severe issues when consumed in large amounts.

Unripe Tomatoes and Green Parts

The harmful solanine and tomatine compounds are mostly found in unripe tomatoes and the green parts of the plant, such as the leaves and stem. To avoid these risks, be sure to remove all green parts and only feed ripe, red tomatoes to your dog.

Tomato-Based Products and Their Safety for Dogs

Tomato Sauce

While tomato sauce is made from tomatoes, it often contains added ingredients like sugar, spices, and onions, which can be harmful to dogs. It is best to avoid feeding your dog tomato sauce and instead stick to plain, ripe tomatoes.


Ketchup is another tomato-based product not recommended for dogs due to its high sugar content and other potentially harmful ingredients. To avoid any health risks, it's best to keep ketchup out of your dog's diet.

Salsa and Other Tomato-Based Condiments

Similar to tomato sauce and ketchup, other tomato-based condiments like salsa may contain ingredients that are not safe for dogs. Stick to plain tomatoes to avoid any potential risks.

Safe Tomato Consumption for Dogs

Moderation is Key

When feeding tomatoes to your dog, remember that moderation is important. As a general guideline, a dog can safely eat about one small tomato per 20 pounds of body weight per day. Be sure to adjust the amount based on your dog's size and weight.

Proper Preparation

Remove all green parts (stems and leaves) and ensure the tomato is ripe before feeding it to your dog. Cut the tomato into small pieces for easier consumption and digestion.

Monitoring Your Dog's Reaction

After introducing tomatoes to your dog's diet, observe them for any signs of an adverse reaction or allergy. If you notice any negative changes, consult with your veterinarian.

Alternatives to Tomatoes for Dogs

There are many other fruits and vegetables that are safe and healthy options for dogs, such as blueberries, carrots, and green beans. Incorporating a variety of fruits and vegetables into your dog's diet can promote optimal nutrition and overall health.


In moderation and when properly prepared, tomatoes can be a healthy and tasty addition to your dog's diet. Be mindful of portion sizes and avoid feeding your dog any tomato-based products that may contain harmful ingredients. Always consult with your veterinarian before making significant changes to your dog's diet, and monitor their reaction when introducing new foods.
