Can dogs have tomatoes?

Tomatoes are a popular fruit enjoyed in many dishes, but when it comes to sharing with our canine companions, pet owners often wonder if they're safe. The answer is both yes and no. Dogs can eat tomatoes in small amounts, but only when they're fully ripe and red. Some parts of tomatoes are toxic to dogs.

In this guide, we'll give you some important considerations to keep in mind to ensure your furry friend's safety.

Can puppies eat tomatoes?

Puppies should generally avoid tomatoes. Their developing digestive systems are more sensitive than adult dogs, making them more vulnerable to potential stomach upset. Additionally, puppies are smaller in size, which means even a small amount of harmful substances can have a greater impact on their bodies.

Are tomatoes bad for dogs?

Ripe, red tomatoes are not inherently bad for dogs when fed in moderation. They contain beneficial nutrients like vitamin C, potassium, and fiber. However, certain parts of the tomato plant contain solanine and tomatine, substances that can be toxic to dogs.

The green parts of tomato plants (leaves, stems, and vines) contain higher concentrations of these toxins, as do unripe (green) tomatoes. For this reason, you should never allow your dog to eat:

  • Green, unripe tomatoes

  • Tomato stems

  • Tomato leaves

  • Tomato vines

Signs of tomato poisoning in dogs

If your dog consumes green tomatoes or parts of the tomato plant, they may develop tomatine poisoning. Watch for these symptoms:

  • Excessive drooling

  • Loss of appetite

  • Vomiting

  • Diarrhea

  • Lethargy or weakness

  • Confusion

  • Dilated pupils

  • Slow heart rate

  • Abnormal heart rhythm

  • Tremors or seizures

  • Muscle weakness

If you notice any of these symptoms after your dog has been around tomato plants or eaten green tomatoes, contact your veterinarian immediately. While tomatine poisoning is typically not fatal, it can be serious and requires prompt veterinary attention.

How to safely share tomato with your dog

If you want to share tomatoes with your dog, follow these guidelines to ensure your pup's safety:

  • Only offer ripe, red tomatoes. Choose organic tomatoes when possible.

  • Remove all stems, leaves, and green parts.

  • Wash the tomato thoroughly to remove pesticides.

  • Cut the tomato into small, bite-sized pieces to prevent choking.

  • Start with a very small amount to see how your dog reacts.

  • Only offer tomatoes occasionally, not as a regular treat.

Remember that moderation is key. Even safe foods can cause digestive upset if introduced too quickly or in large amounts.

Can dogs eat cherry tomatoes?

Yes, dogs can eat cherry tomatoes, but the same rules apply. They should be fully ripe, and you should remove any stems or leaves. For smaller dogs especially, cut cherry tomatoes in half to prevent choking hazards. As with regular tomatoes, only give cherry tomatoes occasionally and in very small amounts.

Can dogs eat tomato soup or sauce?

No, dogs should not eat tomato soup or sauce. While the tomatoes themselves might be safe, commercial tomato products often contain ingredients that are harmful to dogs, including:

  • Onions and garlic (toxic to dogs)

  • High levels of salt

  • Added sugars

  • Herbs and spices that may cause digestive upset

Homemade tomato soup or sauce with no added ingredients might be less harmful, but it's still not recommended as a regular part of your dog's diet.

Can dogs eat ketchup?

No, dogs should not eat ketchup. Most commercial ketchup contains high levels of sugar and sodium, which can be unhealthy for dogs. Many brands also contain onion or garlic powder, which are toxic to dogs.

Even small amounts of ketchup can contribute to obesity and other health issues due to the high sugar content. It's best to avoid giving your dog any ketchup or tomato-based condiments.

How to prevent tomato poisoning in dogs

To keep your dog safe from potential tomato poisoning:

  • Keep tomato plants fenced off in your garden.

  • Store tomatoes where your dog can't reach them.

  • Supervise your dog outdoors, especially around gardens.

  • Be cautious with food scraps that might contain tomato stems or leaves.

  • Always clean up fallen tomatoes promptly to prevent your curious pet from sampling them.
