Health benefits

Many people wonder whether tomatoes are poisonous to dogs. Pet food companies use tomatoes in their formulas because they are so full of nutrients & other important stuff! Tomatoes are suitable for dogs, so it stands to reason that they have some benefits.

  • Tomatoes are powerful antioxidants and contain a range of essential vitamins & minerals, including potassium, vitamin C & vitamin K. The quality of tomatoes can make a significant difference in the amount of these healthy nutrients your dog consumes. 
  • Tomatoes are rich in both soluble and insoluble fiber. Fiber is helpful for digestion and maintaining the blood sugar levels of your dog. It also helps to remove toxins from the body. Whole tomatoes have less fiber than pomace, as they do not contain the liquid removed from pomaces.
  • Tomatoes contain a substance called lycopene, which helps grow strong bones and reduces the risk of stroke.


Tomatoes are safe for dogs, but only when they are ripe. Unripe tomatoes contain solanine, which increases with time. Once it reaches the mature stage, this poison decreases quickly.

Tomatoes also contain a potentially toxic element called tomatine. Consuming large amounts of it can be hazardous to dog health, but ripe tomatoes have such a low amount that even if your pet wolfs down more than you’ve ever imagined, they will not get sick.

Unripe tomatoes contain more tomatine, but the difference is probably not significant. The tomatine levels vary from stalk to leaves—with the highest levels found in the flowers.

Dogs are more likely to experience mild gastrointestinal upset when they eat tomato plants. The symptoms include vomiting, diarrhea, weakness, and appetite loss. Larger grazing animals have the most potential for tomato toxicity due to their high volume of consumption. That being said, there is still a possibility that symptoms could be even more severe in small animals because of their limited ability to process said plant material.
