My dog has a fungal infection on her neck and nipples. Not working.
The first thing I would want to ensure is that this is in-fact a fungal infection. Since you have seen multiple doctors, I'll assume they diagnosed it through a fungal culture or a positive response to a UV light. If this has not been done, then I highly recommend you have it done.
If it's definitely ringworm, then you will have to treat this for a long time before it goes away. It can take a few months sometimes. The terbinafine cream is helpful, but for an infection that has spread all over the body, I would be giving the dog antifungal tablets. You will need a veterinarian to prescribe these.
Your location is showing as the UK, so I am surprised that you were unable to find expert doctors. Have a look at this website and see if you can find a veterinarian near you: http://findavet.rcvs.org.uk/find-a-vet/
I hope this helps, but if you require further assistance, you are welcome to start a consult.
