Tomato leaves and stems--and technically tomatoes themselves-- are part of the nightshade family, something thats incredibly toxic to both dogs and humans. You should give the dogs a bit, monitor closely, for a day or two. In theory tomatoes are just as healthy for humans as they are for pets, but like humans there's an elevated chance of allergic reaction.
I'd give it only in small amounts due to the acidity myself. My dog is a garbage hound who's eaten just about everything that wasn't tied down--including chocolate-- so I think they are alot hardier than we give them credit for, but still warrants caution when introducing a new food.
