Tomatoes belong to the large plant family of the nightshade family. This affiliation implies the content of toxic solanine in all green parts of plants. People are plagued by severe stomach pain and nausea after eating a single unripe green tomato. This also applies to dogs.
- never feed your four-legged friend unripe, green tomatoes
- there is nothing wrong with eating fully ripe fruit
- the green fruit stalk should be cut out first
- If a dog in the garden nibbles at the home-grown tomato plants out of high spirits, intervene immediately
The solanine content only decreases with advancing maturity. The alkaloid in tomatoes cannot be broken down by cooking or frying because it is heat-stable.
