You may not have any more time to waste.......Puppies go downhill very quickly......If this is the beginning of Parvo, without immediate treatment, it is usually fatal! Has she had her vaccines? I sure hope so!
Get your girl some help today! She is depending on you for her medical care just as a child would.........Make the call, NOW! Good luck
Please, do not add any more salt to her water....
Please do take your puppy straight to the vet or the emergency vet right now.
I hope she will be OK
