Help with Betty's Vet Bills

Hello everyone! This sweet stray pup wandered up to our house on September 14th and has clearly been lost/abandoned for some time now. I called every shelter and humane society in the area, but they are all completely full and cannot help us. After keeping her confined to our kitchen for a few days, we were able to find her a temporary foster since we cannot keep her at our house with our other pets. We are hoping to find her a permanent home after receiving her vaccines and spay surgery. We took her to a veterinary clinic and were able to get her fully vaccinated through donations we have received so far, but unfortunately, we found out that she has heartworms and will need very expensive treatment which is around $1,200 despite complications. As a newly college graduate, I am unable to afford these costs, so I am looking for donations to help her get the treatment she deserves. She is the sweetest girl and does not deserve to be taken to MAS where she will likely be euthanized. I am hoping that through all of your donations, we can give her the care she needs and find her the perfect home. Any exceeded or unused funds will be donated to the animal shelter to help other strays in the Memphis area. I would love to be able to continue finding foster homes for stray animals and raising donations in the future. We all need to come together to help solve this major problem of strays in Memphis! Thank you for all of your help.
