I'm sorry you and your dog are going through such a stressful time, Keva
In Wisconsin, the first drug of choice for tick disease is doxycycline. Normally we see an improvement in symptoms within the first 48 hours. But it depends on the severity of the case, whether it's become a chronic infection, and the overall health of the animal.
If your dog isn't drinking and continues to vomit, she needs to go back to the vet. It's very easy for a dog to dehydrate under those conditions, especially if it's warm there.
Good luck with your girl.
Please keep us posted on her progress.
