If you are ever in doubt about what your dog can or can’t eat then simply don’t feed the food to him. Ask your vet first. Tomatoes for instance aren’t bad for your dog when given in small portions. Your dog may not even like them. If he does, give him cut up pieces but don’t let him take a tomato from the garden. Un-ripened tomatoes and tomatoes with the leafy greens attached can be dangerous. Tomato lives can contain toxins or poisons that can harm your dog. The tomato is in the same family as the potato. They are members of the night shade family, which is a plant species that contains toxic alkaloids that can be harmful to pets. If your dog has ingested a large quantity of this toxin then he may show signs of excessive drooling, vomiting, diarrhea, drowsiness, confusion, weakness, behavior changes, dilated pupils, or even a slowed heart rate.
