My name is***** and I am sorry to hear that Oliver is sick. Just to clarify, I am going to talk about the sequence of events that led you to the vet this morning:
First- why did you start giving Oliver zantac? Was he vomiting already at home? Does he like to eat stuff he shouldn't?
Next- aspiration pneumonia is common in dogs that have vomiting. Their larynx doesn't close tightly like ours does. The antibiotics that I would use are Enrofloxacin (Baytril) and Clindamycin for pneumonia. But these may be several times a day, so it looks like more.
If a dog is vomiting, we have to figure out why. A barium series is a great way to determine if a dog has an intestinal blockage. If your vet is recommending surgery, I would suspect that the barium stopped moving through the intestines indicating a blockage. Without surgery, most dogs will die from a blockage.
What other questions do you have? How can I help you decide what is best for your dog?
I will be on-line for about another hour and then will be back this afternoon.
Best regards, ***** ***** this answer helps you.
Feel free to contact me if you have any more questions.
