R U kidding she needs to go to the Vets immediately would u sit still if ur child were exhibiting the same symptoms.
This forum is not for Emergencies......I agree w/ Ginger.....This could be any number of things that only a Vet will be able to diagnose. (Not an online forum)....
Some Puppy illnesses can be fatal!!! Please, get her to the Vet ASAP, before she gets worse.....Let us know how she's doing when you can....Karla
A little pup like she is can get very dangerously dehydrated if the vomiting continues. Has she had her innoculations? Does she also have diarrhea? Could she have eaten anything she shouldn't have?
Don't try to make her eat. Get her to the vet. In the meantime see if she will drink small quantities of Pedialyte. If you haven't got that use boiled water (cooled) with a tiny amount (a pinch or two) of salt, and a teaspoon of honey or maple syrup.
