Fun Facts About Tomatoes

Tomatoes originated in western South America and the Aztec word tomatl was the inspiration for the Spanish word “tomate”, from which the English word tomato was formed. The Spanish first discovered the tomato from their contact with the Aztec civilisation during the colonisation of the Americas.

Interestingly, a legal dispute in the United States in 1887, lead to tomatoes being classed as a vegetable by the US Supreme Court in 1893. This was because they are generally served with dinner and not dessert. Botanically, tomatoes are still classed as fruit.

Are Tomatoes Safe for Dogs to Eat?

The question of “are tomatoes safe for dogs?” is a bit more complicated than a yes, no answer. Some parts are perfectly safe for your dog to consume, while others are not.

It is important to remember that tomatoes are part of the nightshade family, and parts of them contain substances that can be toxic in large doses. While poising from overeating tomatoes is quite rare in dogs, it is best to know what parts to avoid.

Below we have listed some of the parts of a tomato or tomato plant you should never give to your dog.

  • Leaves
  • Roots
  • Stems
  • Green, unripe tomatoes

The parts listed above are toxic to dogs because they contain a few different components that are harmful to dogs, including solanine (tomatine in tomatoes). Solanine is found in the leaves, stem and in green tomatoes, along with plants in the same family. It is harmful to dogs in large quantities and can cause some serious health complications.

While it is great news that ripe tomatoes are safe for dogs to eat, it is still problematic for those of us who love to grow our own tomatoes in our garden.

Keeping dogs away from certain places is always a battle and stopping them from chomping down on a nice tomato plant is easier said than done. If you decide to grow tomatoes in your garden, make sure you put them in a place where your canine companion is unable to each them.
