If your dog has fever, go to the vet as soon as possible. If dog keeps vomiting, try charcoal pills (coat pills with butter). Don't use milk, it causes diarrhea.
I will say this as politely as i can, "take the poor dog to the veterinarian! " For one thing no one on here will be able to make a true diagnosis. Also, if you kid did the same thing would not you seek immediate medical help?
If your dog has eaten anything they should not have done, you can induce vomitting by forcing the dog to eat a handful of salt. If the Dog had already begun to be sick, you should take it to the vet.
