|below is what i found on a vet website. can't remember where i orginally saw it first.
With the healthful benefits of tomatoes, it would not be surprising for a dog owner to include this nutrient-rich fruit in the diet of the dog. But are tomatoes safe for the dog? Tomato is a member of the nightshade family and as such it is expected to have some toxic effects when consumed. Toxicity effects of tomatoes in humans are generally mild but toxic effects in dogs are more severe so as to result to the death of the dog.
To ward off the toxic effects of tomatoes, dog owners must keep the dog away from unripe fruits. Only the leaves, the stem and the unripe tomato fruit contain the tropane and atropine alkaloids. Dogs are poisoned by tomatine, the substance that is found in the tomato plants and unripe fruits. Excessive drooling, vomiting, diarrhea or constipation are sign of tomato toxicity. Dogs that have ingested green tomatoes will suffer from stomach upsets because tomatine is not efficiently absorbed by the intestines.
The toxin present in tomatoes directly affects the heart and the central nervous system. Accelerated or irregular heartbeats will be noticed in dogs that have ingested considerable amounts of leaves, vines and unripe tomato fruits. Weakened muscles, breathing difficulties and tremors are other signs of tomato toxicity. Dogs severely affected by the toxin can go into coma and can expire.
Tomatoes though are not bad for dogs. Dogs would get the healthful benefits humans get from this fruit. To prevent poisoning, owners have to make sure that the pet is given only ripe tomatoes as the amount of tomatine contained by the fruit is considerably reduced during the ripening process.
