My baby girl Zoey

Zoey is my emotional support animal. 5 yrs ago she saved my life when I had a bad head trama. Now she has been on two different antibiotics and needs surgery next Friday. We have half the money to pay. But are still in need of the 400.  I am unable to work at this time die to health. She is a very loving dog. Any help would be appreciated. Shes my baby. Thank you.
