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.

My puppy ate unknown greens and is vomiting. Is it an emergency?

Oh no, that was naughty of Oliver to eat those greens! Certain varieties of the lily are toxic to dog, and eating these varieties can cause GI upset, anorexia, and tremors. You have seen some GI upset, and I can give you a home remedy to see if that helps him. Withhold food for 8-12 hours, then 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.

My puppy threw up whole food & pine needles after recent shots. Why?

He might have eaten something spoiled that is causing this. withhold food for 8 hours then offer him boiled boneless chicken and rice every 4-6 hours in small portions. if he is eating and not vomiting, continue with this diet for 2 days. After 2 days, you can put him back gradually on his normal food. If he continues vomiting or is not eating, take him to the vet to get treatment.
