This guide breaks down what you need to know about feeding tomatoes to dogs, from safe serving sizes to emergency signs of poisoning, ensuring your pet stays healthy while enjoying occasional treats.

The Toxicity of Tomatoes: Solanine and Dog Safety

Tomatoes contain solanine, a natural glycoalkaloid found in higher concentrations in green stems, leaves, and unripe fruit. While ripe tomatoes are generally safe, excessive consumption—especially of toxic parts—can lead to digestive upset or poisoning.

Why Is Solanine Dangerous for Dogs? – Binds to acetylcholine receptors, disrupting nerve signals. – Causes muscle weakness, tremors, and confusion in severe cases. – The leaves and stems are 10x more toxic than ripe fruit.

Symptoms of Tomato Toxicity in Dogs If your dog ingests a large amount of solanine, watch for these emergency signs: – Excessive drooling – Lethargy or weakness – Stomach pain or vomiting – Difficulty breathing – Seizures (in extreme cases)

Action required: Contact your vet immediately if symptoms appear.
