I think my dog ate some tomato leaves

The leaves of a tomato plant contain the glycoalkaloids alpha-tomatine and dehydrotomatine. These substances are toxic to both pets and people. If your cat or dog eats the leaves, he might experience lethargy, drooling, stomach upset, diarrhea, vomiting and changes in his behavior. Tremors or seizures could also occur. If you have observed or suspect your pup has munched on your tomato plants, it's best to get him to the vet so he can be treated. Poisoning is a serious situation and you should visit an emergency vet if your regular vet isn't available.
