FWIW, you did exactly what needed to be done to get rid of that pain ful leg and give her a chance at a pain free quaility life.  Everything  appeared to be osteo....and even with a different type of sarcoma, amputation  was the best option.

There are never any guarantees  one way or another with chemo.  Some   seem to bet extended time with it, some get less time than projected.   Some seem to get extended  time without it, some less.  So always a crap shoot when it comes to chemo.  And yes, fiances are a hurdle for many, if not most.  You have already gone above and beyond what some can do financially. 

Did she ever have CT scans after the amp?  Again, most can't  afford those anyway, but just curious.

How I wish I had some answers for you always seems like more questions though.  

Go back to still getting another opinion....even of it's only from a Vet who will try fluids and take a good look at all the meds she is taking to see of eating can improve.  She's on so many different meds for tummy, appetite, nausea,  antibiotic,  etc, just wondering  of any can be eliminated. 

One thing you might want to do is hop over to Ask A Vet thread.  She's a member who is a Vet and volunteers here trying to help when she can.

I have to head to work now, but I'll be glad to help you so that when I get in tonight.  And of your like to send more photos od the lumps I'll be glad to ppst either here or on Vet thread.

(((((((((Hugs)))))))

Oh....and this was my response in part to her email that accompanied  the pictures, etc.  Ao far, no one outside of thos clinic has seen Molly.  And I believe  this Vet who wrote thos response  hasn't  actually seen her either.....just pictures of the lumps.

Anyway.....this is what I wrote back:  if I'm way off base, let me know!
