Hi Sherry
As your post is from a few days ago I guess your dog has either recovered from this vomiting or it did indeed develop into an emergency.
Frequent acute vomiting can develop as a symptom from a variety of causes. It can be infection, disturbed digestive function or something completely inappropriate that the dog ate such as a foreign object that gets stuck and blocks up the intestines. The only thing you can do at home is to try to keep fluids in your dog by giving him small drinks very frequently until the bout passes. If it has passed within 24-48hrs then that's great and he recovered. If vomiting continues on beyond this time a dog will become dehydrated which is life-threatening and needs the help of a vet to treat, regardless of what the cause of vomiting is.
