As much as we might like to help here, you are going to have to depend on your local vet.

I agree with labman. Unfortunately, there could be so many things going on, especially if it's not immediately recognized by the vet... They should be able to tell you what's going on as soon as the test results come back.
Is your puppy at the vet now? Did they tell you how long it would take for the test results?

What tests are they running? How do you know they are running 'everything'?

If one veterinarian's results are inconclusive, don't hesitate to find another vet. I have never known a scenario where a vet says, "Sorry, we've done every test and x-ray but still don't know what it is."

That just happened to my lab and it was a inlarge pancreas, they gave her antibiotics and she is now doing well.
