Sick fur baby 🐾 please help ❤️

During cyclone gabrielle amongst everything our fur baby turina (toots or tu-te fruity) was hit by severe rash/constant loss of hair vets cant seems to pin point the issue,most likely sewer water being likely culprit (vet) which has lead to antibiotics (dicloxacillin) steroids (prednisone) on a long term basis ,im doing my best,getting totally overwhelm with vet visits bills,its gotten to a point where im asking friends for there leftover pills just doing what i can 😢

Some images are not good to post🙏

Thank you ❤️
