Pizza! Anybody order a Pizza?! How about a salad? If so, no problem! Everything is just fine. Are you growing tomato plants in the garden though? If the answer is yes, watch that your pet is not chewing on the leaves or stems of your crop. It can cause them some GI upset such as vomiting and diarrhea. Unripe green tomatoes can cause the same concerns. Tomatoes are not necessarily "toxic" to pets, they just don't absorb some of the plants chemical make-up properly. Any reaction to these plants usually subsides within 24 hours. In order for your pet to have major concerns, your dog (or cat) would need to eat about 75-500 tomatoes, depending on their body weight to be lethal. Can you even imagine?! Your pet would likely vomit from sheer amount of food before they ever ate enough tomatoes to be deadly.
