Poor Bobby sounds like he is feeling unwell! I would avoid giving him tea as well, especially if it has milk in it. Dairy causes GI upset in dogs, and it may be making his vomiting worse. The only liquid he needs, even when sick, is water. He could be suffering from a severe GI illness, may have eaten something rotten, or could have a foreign body. It's a good idea that you have kept him off food since, and if he has been off food for 24 hours, feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the vomiting continues in the absence of food, he vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away.
