Can tomatoes be toxic to dogs or cats?
Tomatoes are a member of the nightshade family, and IF the dog or cat ate enough of the foliage, stems, etc toxicity is definitely possible, although mild GI upset is the most likely scenario.
Tomatoes contain alpha-tomatine. The concentration from highest to lowest is flowers> small stems > leaves > calyces > small immature fruits. Very little tomatine is in ripe fruit (which is a really good thing considering how much I love tomatoes).
The estimated toxic dose, assuming 5% tomatine in the leaves, is 1 kg leaves/ 100 kg bw. So pretty much true toxicity is a large animal thing.
