Help Evie who has been attacked by dogs

My beloved dog, Evie was attacked by the neighbors 3 dogs who dug under the fence and came into my yard.  I believe my little Papillon was the original target but Evie took up the fight.   She was severely injured and almost lost her life.   I have already borrowed $2,000 to cover vet bills and the fight is just beginning.  I don’t have much of a savings account and basically live paycheck to paycheck, as do many others.    My beloved dog is fighting for her life and I hope she recovers and goes on to live happily with me.  I could use any help you are willing to give.  My dog has been a faithful companion and as long as she has the will to live, I am willing to make sure she gets that chance.  Thank you for any help you can give.
