Green tomatoes: why the unripe fruit and the plant are off limits
Avoid
No safe form of green tomato is listed for dogs, and unripe fruit and tomato plant parts are both named as unsafe, so none of it should be fed on purpose.
Not worth offering as normally served.
No, avoid green tomatoes. Unripe fruit and tomato plant parts are the unsafe forms, and exposure has been linked to gastrointestinal irritation, incoordination and weakness. No preparation is listed that makes green tomatoes safe to feed on purpose. If a dog eats some, contact a veterinarian or animal poison control promptly.

Which form of green tomatoes the sources actually cleared
This verdict covers green tomatoes in the sense of unripe fruit, and it reaches wider than the fruit alone: tomato plant parts are named as unsafe too, so the plant material within reach in a garden counts, not only what ends up in a kitchen. It does not cover ripe tomatoes, which are handled as their own food elsewhere. Fried, pickled or relished green tomatoes are not listed as separate forms here, so there is nothing on record to suggest a cooking method changes the answer for unripe fruit.
Preparing green tomatoes for a dog
There is no preparation routine for green tomatoes, and that absence is the point. The only rule recorded is not to feed them intentionally, so there is no cooking, peeling, seeding or portioning step to get right, because no such step is offered as a way to make the food acceptable. No particular ingredient or processed form is flagged for avoidance either, which means the concern is the unripe fruit and the plant material themselves, not something mixed in with them.
What actually goes wrong
- GI irritation, incoordination and weakness reported from plant/unripe fruit exposure
Three effects are on record for exposure to green tomatoes and tomato plant material: gastrointestinal irritation, incoordination, and weakness. In plain terms that is an irritated digestive tract, plus a dog who may move unsteadily or seem unusually weak. The hazard is rated 3 out of 4. No medical condition or type of dog is singled out as being at extra risk, so the warning is not aimed at a subgroup. If a dog eats green tomatoes or chews the plant, contact a veterinarian or an animal poison control service promptly, and do not give home antidotes or induce vomiting unless a veterinary professional instructs you.
What these sources do not settle
Two sources sit behind this, graded B+. They settle that green tomatoes and tomato plants are worth avoiding and which signs have been reported, but not how much a dog would have to eat before anything happens, how ripe is ripe enough to stop counting as green, or how quickly signs show. No treat allowance is recorded, which fits a food you are told not to offer at all.
