Pyper needs surgery

Pyper was born 3-14-20.  She is a beautiful german shepherd pup! So loving, and   full of energy.  Once we started transitioning her on to dry puppy food we noticed she started crying in pain and regurgitating her food up.  If we gave her wet food  with puppy formula she was fine, the minute we added any dry food we got the same reaction. Pyper began to look thin so, we took her to the Vet.  Pyper was diagnosed  with a congenital problem called
Vascular Ring Anomaly.  This is a band of tissue that is encircling and constricting her esophagus.  It is a tissue band that   is remnants of fetal blood
vessels that should have dissolved before birth.  It did not dissolve away on Pyper so she will need to have it surgically cut.  I have contacted a few
different animal surgical veterinarians and all are quoting basically the same amount  $3500 to $5000.   Currently this isn't feasible for us to be able to afford for her so, I am searching out help to get her the surgery she needs. At the same time Pyper came into our lives I found out I have cancer, she has been there for me as I am going through chemotherapy and radiation treatments, she's my little comfort girl!! I don't want to lose her.  Any help will be  greatly appreciated!!  Any money left over after the care for Pyper will be donated to the local animal shelter in our town.
