Whether ripe or unripe, tomatoes contain traces of toxins (solanine and tomatine). Ingesting large quantities leads to tomato toxicity, otherwise known as tomatine poisoning.

Solanine is concentrated in unripe tomatoes and other parts of the green foliage.

It mainly causes stomach irritation resulting in gastrointestinal upset.

That said, dogs are unlikely to ingest an amount large enough to cause tomatine poisoning.

However, for young pups, even a small amount could lead to poisoning due to their small size.

What are the symptoms of tomatine poisoning?

The severity of the symptoms depends on the number of unripe tomatoes ingested, dog size, and preexisting medical conditions.

Symptoms include;

  • Poor appetite
  • Gastrointestinal upset (vomiting, diarrhea)
  • Drowsiness
  • Muscle weakness
  • Behavioral change
  • Lethargy
  • Seizures
