Help with Athena's treatment

Our beautiful rescue dog, Athena, is currently undergoing a long treatment for heartworms. When we rescued her, she was greasy and dusty, and she was ill with respiratory issues, as well as a heartworm diagnosis we were told she was currently in treatment for. We completed her treatment as prescribed, only to find out that she still has heartworms...

She is currently on 3 different medications, and is receiving 3 rounds of powerful medical injections. The first visit tapped us for the rest of our small remaining savings (recently bought a house, so free funds are low) and we are now doing everything we can to ensure that our furry baby is taken care of, so that she may continue to live the long, happy, and active life she deserves.

Her remaining rounds of shots will be taking place early in 2021, and then she will need about 2 months of activity-restriction to fully recover and ensure she does not get post-treatment infections. 

Thanks you for any and all help!
