What ingredients are in tomatoes?

Tomatoes pack a lot of healthy ingredients that benefit both humans and animals.


One scoop of raw tomato paste contains;

  • Vitamin C
  • Vitamin E

  • Carotenoids


Both humans and pets can benefit from the antioxidant properties of tomatoes.

But why are vet’s saying that tomatoes are a potential health hazard to dogs?
