The leaves and stem, along with green or unripe tomatoes, are toxic to your pet. Why are parts of the tomato plants and green ones dangerous? It is because raw tomato and the plant itself contain Solanine and Alpha-tomatine (or just tomatine), which can be harmful to your dog’s body.

Tomato plants are members of the nightshade family and plants in this grouping usually have toxic substances. However, these plants, including the tomato, are not harmful to humans (at least in small quantities), but it tends to affect dogs more strongly.

The good news is that ingesting solanine and tomatine won’t harm your pet immediately. However, if you overfeed your dog with green tomatoes, then the two substances will have negatively affected the canine’s body. Therefore, applying moderation when it comes to serving your dog tomatoes is necessary.

  • Loss of coordination
  • Cardiac effects (may vary, but the dog’s heart is always affected)
  • Muscle weakness
  • Body tremors
  • Constipation
  • Dry mouth
  • Dilated pupils
  • Difficulty in breathing

If your pet shows these signs, you need to stop giving it tomatoes for a while and see if things will improve eventually. But my best advice would be to go to a veterinarian for consultation and treatment. Better to be safe than sorry when it comes to tomatine and solanine poisoning.
