Can Dogs Eat Tomatoes?
Ripe tomato flesh is generally safe in small amounts, but green tomatoes, stems, and leaves contain solanine, which is toxic to dogs.
Ripe tomatoes are OK — green parts are toxic
Ripe red tomatoes contain only trace amounts of solanine and tomatine, making the flesh generally safe in small quantities. However, the stems, leaves, and unripe green tomatoes contain higher concentrations of these toxic glycoalkaloids. Dogs who eat from tomato plants in the garden are at higher risk.
