Tomatoes, with the scientific name Solanum Lycopersicum, are known to be a nutritious source of vitamins and nutrients if consumed in appropriate quantities. They are not just beneficial for humans, but for dogs as well.  This is why dog food manufacturers include tomatoes (in the form of tomato pomace) as a component of their products.

Tomatoes are rich in lycopene, an antioxidant that primarily fights off harmful free radicals, reducing the risk of heart disease. An average-sized tomato has a low-calorie content (around 18 calories) and high fiber level (1.5 grams), which greatly aids in digestion.

Other vitamins and minerals in tomatoes include the following:

  • Beta-carotene and Vitamin A – essential for the immune system, vision, reproduction, and proper organ function.
  • Vitamin C – important in the growth and rejuvenation of tissues.
  • Folate – also known as vitamin B9, folate is critical in tissue and cell growth.
  • Potassium – essential for regulating cholesterol, controlling blood pressure, and preventing heart diseases.

How Is It Bad for Dogs?

Unripe tomatoes and green parts of tomato plants like the stems, leaves, and stalks, contain two toxic compounds: tomatine and solanine, toxins that could be harmful at high levels. This means that a few bites on unripe tomatoes and a couple of leaves won’t pose serious health issues to canines.

If you want to prevent your dogs from eating large amounts, make sure to situate your plants far from your dog’s reach or put some barriers. As the tomato ripens, its tomatine levels decrease, making ripe tomatoes safer.

Products containing tomatoes like juices, soups, and sauces, could be unhealthy for dogs, especially if they carry sugar, salt, and other artificial ingredients. To control the tomato content of food, you can make your tomato-based products.

A deadly condition called anaphylaxis is also possible but in super rare cases. If you notice alarming signs or symptoms, stop giving your dog tomatoes immediately. Or if the symptoms persist, contact your vet.

What Are the Clinical Signs of Tomato Poisoning?

If your four-legged friend has consumed some green parts of the tomato plant, observe for some signs of tomatine poisoning. According to the American Kennel Club, the clinical signs include the following:

  • Uncontrollable heartbeat
  • Diarrhea
  • Lethargy
  • Loss of coordination
  • Seizures
  • Tremors
  • Hypersalivation (excessive drooling)
  • Drowsiness
  • Loss of appetite
  • Confusion

These symptoms are rare, but they are also treatable. Any symptoms you notice above can warrant a visit with the vet. If your dog is experiencing diarrhea or vomiting, the vet might administer fluid therapy, which helps to flush out toxins and treat dehydration.

Another treatment is gastric lavage, which involves putting a tube through the dog’s stomach to flush out toxins.

How Do You Give Tomatoes Safely?

Be careful of the source

Make sure you know the background of the plantation where you will be picking your tomatoes. Avoid sources that have been applied with fertilizers, pesticides, and herbicides as they can cause your dogs to become sick.

Choose the ripe ones

Before giving tomatoes to your lovely pet, pick the bright red ones, while removing the stems, vines, and leaves. How do you know a ripe tomato fruit? First, the tomato’s skin should be glossy, and its redness must be deep and bright.

Clean the tomato

After picking the tomato from the source, it’s important to rinse it well to ensure safe consumption. Using your hands, rub the tomato’s sides. Don’t use chemicals like soaps, detergents, or bleach to wash them, as their flavor could be poisonous.

Don’t add unnecessary additives

Many foods can be eaten by dogs, but additives like salt, garlic, and onions are harmful to them. These ingredients can give your dog an upset stomach. For example, garlic contains thiosulfate, which may be safe for humans but highly toxic to dogs.

Everything about onions is also toxic, from its leaves, flesh, and juice. No matter what type of rigorous food processing or cooking you do, your dogs must be kept away from them.

Read the labels

If you want to give your dog tomato-based products like tomato sauce or ketchup, read the list of ingredients on the label. If there are unsafe ingredients, steer clear of them.

A common ingredient of tomato ketchup is fructose corn syrup. This is not toxic but it’s not recommended for your dog because of its high sugar content. This means that regularly consuming products with this ingredient can increase the risk of obesity and diabetes.

Know your dog’s stomach

If your dog has gastroenteritis or stomach-related issues, better not give tomatoes as it could aggravate them.

Give in small amounts

Don’t give a fully-loaded meal of tomatoes to your dog, but provide incrementally and observe if your dog manifests signs of allergies. If none, then it’s okay for your dog as a snack.

Avoid canned tomatoes

Canned tomatoes contain high levels of sodium, which can lead to your dog’s dehydration or worse, salt poisoning.
