I have an eighth month mix breed, part chow/husky who seems to be getting worse. She cannot keep any of her food down or liquids for that matter. She throws up everything that she ingests. She's has been given meds that initially looked like they were helping but last few days they do not seem to help. I have taken her to two Vet.'s, the second one giving her an X-ray and blood work which turn out to be normal... xrays do not show anything either... Not sure what to do next, any recommendations?

Unfortunately I won't be able to tell you anything that the vet probably hasn't told you already.
Is your puppy a chewer? There are some things that won't be that apparent on an x-ray film, things like plastic bags from the grocery store, some bits and pieces of soft toys, the wrapper off a deli cooked hen or sandwich meat.
And some films are just not good quality films, digital films are great, but not every clinic has access to digital.
I would have the vet that took the x-rays review them again and re-examine him.
But without a definite answer as to what is going on, don't be surprised if they suggest an exploratory surgery.

Parvo test?
