my dogs cancer...?

I can't tell you the whys, but what does the vet suggest as a course of treatment.  You don't know at this point without at least a biopsy that it IS cancer??

I believe that cancer cells feed on grains, so it would be important to go with a high quality grain free food.  And do follow up with the vet regarding treatment.

well the vet says she has no guess of whats going on and i dont even have anuff money to think about paying for a biopsy

Dogs of any age can get cancer -- however -- *where* was the mass?  Dogs can also swallow some pretty strange things.

How far are you from your state's vet school -- sometimes a vet school can be way cheaper than you might think -- you deal with students but often the care is not expensive.  You might want to consider Care Credit as well.

his lungs, and i dont know of any vet schools.

 I'm so sorry to hear about your dog. In this economy, a lot of folks are having problems affording vet care for their pets. Have you considered working out a payment plan with your vet? It wouldn't hurt to ask them about it. I'll be keeping you and your pup in my thoughts;{{{hugs}}}
