Can I give my dog soup if she hasn't eaten for days now and has been throwing up since thanksgiving because I gave her table food?

What did the vet say to do?

If your dog hasn't eaten for days, and is throwing up, it's long past time to go to the vet.

No, do not give your dog soup. There is a reason your do is vomiting non stop.

Go to the vet

SERIOUSLY?

Table food is a HUGE no-no, especially at Thanksgiving. If he got into bones he may have an obstruction. If not, he probably has pancreatitis.
You need to get your dog to the vet. I don't even know how this is a question. Do NOT give it MORE people food.
