What? Suggestion----Tell her to take this puppy to the Vet immediately.....There are too many things this could be & impossible to guess on a public forum.....We are not Vets & this puppy needs an exam....I'm not even gonna ask how long it's been going on......
Dehydration ALONE can kill a dog, from vomiting & no water...My goodness, what is she waiting for??? She is responsible for getting this dog some medical help!!!! Call her, now!!!! Karla
Totally agree with Karla! This dig needs to be seen by a Vet and soon! Absolutely no way to guess at a cause.
